A list of Spanish fangames you can consider for translating; really only here so they can be on your radar if you haven't seen them before

1. A Pokémon Story: Lilien When They Weinen - (2 gym demo, probably won't be updated a for a while; made by team who created Old World Dawn, etc.)
2. Pokémisterios S.A. - (Complete Liberty Jam game, which is essentially the Spanish version of Game Jams.) P.S. This one looks incredible, that's all I'll say.
3. Pokémon Abismal - (1 gym demo, has a multiverse version and an non-multiverse version, since it takes a bunch different IPs and Nintendo games into its story.)
4. Pokémon Altar - (Fully Complete game which I'm surprised I haven't seen anyone talk about since the art and direction look really nice.)
5. Pokémon Amanecer - (2 gym demo, which seems dead, but it looks cool.)
6. Pokémon Arcania - (2 gym demo, I'm pretty sure this is old version of Obelisco/Orisa since it's the same team, but I don't know.)
7. Pokémon Astral - (Complete game, most likely the older version of Abismal though, since it's the same team and has similar things that Abismal has, which I explained above.)
8. Pokémon Axón - (6 gym demo, but Beta 4 should be coming out this year I believe. Based off of Russia I believe.)
9. Pokémon Blue Melody - (2 gym demo (I think) not a lot of images to help figure out what this is about, but has good graphics though.)
10. Pokémon Brio - (2 gym demo (I think) I don't remember you talking about this game, but it looks fantastic.)
11. Pokémon Burnt Horizon - (3 gym demo, made by the guy who made Gadir, though this one is being translated as we speak, but here just so you know about it.)
12. Pokémon Club de Combate - (No gym fangame I'm pretty sure, nice art and different and unique story from what I've seen.)
13. Pokémon Conquerors - (A GBA version of Pokemon Conquest; It's in its first demo though.)
14. Pokémon Cronicas de Cintia - (3 gym demo, pretty sure you talked about this game when watching the Spanish Fangames direct that was on two years ago, but here it is anyway.)
15. Pokémon Distorsion - (3 gym demo I believe. I can't even remember where I found this, but it was in like SUPER alpha from what I remember, since it had its own launcher and everything at one point. I have the game downloaded, but I can't find the page for it.)
16. Pokémon Dualidad - (I don't how many gyms the demo I downloaded has, but on their twitter, supposedly something is coming out in 2027, maybe new demo or complete game, I don't know.)
17. Pokémon Estrellato - (1 gym demo, has cool looking graphics and fakemon.)
18. Pokémon Evol - (All 8 gyms WITHOUT post-game.)
19. Pokémon Excelsis - (MIGHT be complete, but I'm not sure. Rouge-like look and gameplay from images.)
20. Pokémon Existence - (2 gym demo, cool fakemon and environments.)
21. Pokémon Future - (9 gym demo, you might know about this game since it is made by the people who created Hidden Place.)
22. Pokémon Galicia - (I don't know how many gyms, but it is in its third demo right now.)
23. Pokémon Grunt - (Made by the guy who made Pokemon Isekai. I remeber seeing this game had A LOT of content, and not even finished yet, probably won't be in my opinion, but looks good.)
24. Pokémon Ilíada - (Complete game, that looks very good, though no fakemon I'm pretty sure.)
25. Pokémon La Joya de Arceus - (Can't remember if this complete or just demo, but it's made by Pablus94, and looks like a choose your own path game trying to escape a forest of some kind.)
26. Pokémon Latinum - (4 gym demo with INSANE art, graphics, and fakemon. Can't believe no ones been talking about it.)
27. Pokémon Magnetic - (Complete game I know you know about. But, I downloaded it on their twitter where it says the English version is available, but there's no option given to put it in English, so I'm a bit confused about that.)
28. Pokémon Ozone - (2 gym demo, cool graphics and art that still updates once in a while.)
29. Pokémon Pirita - (2 gym demo, has a bit of dungeon-esque feel to it.)
30. Pokémon Prime - (2 gym demo, looks superhero-esque, but I'm not sure.)
31. Pokémon Reivenger - (3 gym demo, about becoming a cop with really good graphics and fakemon.)
32. Pokémon Roseta - (Up to the fifth day. I'm think you also know about this game, since it is made by BlattaKoala, who has been doing some of the Fangame Directs as of late on his youtube channel.)
33. Pokémon Salitre - (3 gym demo, based on Chile.)
34. Pokémon Sky & Geo - (First demo, but I don't know how many gyms. 
35. Pokémon Sphynx - (I don't how many gyms, but it currently has demo 2. I pretty sure you know this game as well, becasue of the Fangame Directs. Based off of the Mother/Earthbound series.)
36. Pokémon Visiones Etéreas - (3 gym demo I think. Has both good graphics and fakemon/regional forms.
37. Pokémon Weichafe - (13 gym demo, technically complete, but only half of the post-game is done. Also based on Chile, mainly Southern I'm told.)
38. Pokémon Yveltal’s Awakening - (First demo, don't know how many gyms. Really good graphics, art, etc.)
39. Pokémon Zenit - (1 gym demo (I think) Made by Skyflyer.)
40. Pokévengers - Guardianes del Infinito - (This game is too peak NOT to put here. Pokemon version of the MCU with really good graphics. PRobably won't ever get finished, but the fact this was made is a true testament to minds of Fangame creators and should have A LOT more recognition.)
41. Venova Adventure - (A complete game that is getting a complete upgrade they call the 'Reforged' version that is currently in development. So they may or may not have an English version available when the new version comes out, but this has HUGE potential.)

These are some of the games that you should keep an eye on and possibly translate if possible. If you need links to their pages or look at what the games look like, since I have all of these games mentioned downloaded, don't hesitate to reply or contact me if need be. Thanks!
