I'm curious to see what video games actually made it to the big screen and did it right, could be anime, live action, a movie series, doesn't matter, just bring up some of your favorites!
Personal favorite of mine was gun grave! instead of just adapting the bare bones story of the game, it went and gave it an entire in-depth backstory fleshing out the conflicts of the characters as well as adding new ones that made the story much more enjoyable and dramatic.
Kirby Kirby Kirby! He's the star of the show!
Jokes aside, Kirby Right Back at Ya is a solid anime. It's not 1 to 1 with the games but this anime released when the only frame of reference for an actual story was
checks notes Adventure, Dream Land 2, Dream Land 3, Super Star, and 64. Three of those have practically non existent storylines, no wonder they deviated.
Sonic X for all its flaws isn't bad. Chris is overhated imo. He's mildly annoying but IDK I like him better than the cop in the Sonic Movies. I like the idea of the rich kid with neglectful parents with shit else to do, so he latches onto the random ass thing that came into his life. And honestly, that's a perfect reason for his S3 selfishness.
Sonic OVA is great and I'm tired of saying otherwise. Other than dated jokes common in anime around that time and the lack of a story, it captures CD's vibe pretty well. It feels like more a Sonic adaptation than our current Sonic movies tbh. Those movies don't even got the actual locations besides some names and generic backgrounds that you can only theorise is Ice Cap Zone (ignoring all the structures that Ice Cap has)
Darkstalkers OVA is far and away the best adaptation of Darkstalkers
Mega Man Ruby Spears for the memes, Mega Man NT Warrior for the serious pick
Day of Sigma is great. Explains a lot that happens in X1.
Gunvolt had a one shot OVA based on the beginning of the game and I wish it got picked up for a full run cause that shit was awesome
Arcane
Cyberpunk Edgerunners
Speed Racer: The Movie is a cult classic now. People despised it back then and love it now. Me personally, this fills me with joy cause I always loved this movie.
All of Pokemon's movies fit right in to the anime
Scott Pilgrim Vs The World (is this cheating?)
Alita: Battle Angel
