There are a few games/series that have a special place in my heart:
Kingdom Hearts (I kinda grew up with these and even though they can get kinda ridiculous, they are still special to me)
Chrono Trigger (Robots, dinos, swordsmen, time travel, an amazing soundtrack… it makes me so nostalgic)
Castlevania (the metroidvania style ones)
Resident Evil (more so the older ones, but the new ones aren’t bad)
Pokemon (My favorites were Emerald, HeartGold and OmegaRuby, the latter being the last in the series I played. I also enjoyed the Mystery Dungeon ones)
Persona series (4 is my favorite, but it could just be because I started with that one. Great stories, amazing relationships, awesome soundtracks)
Omg I thought the same
