Rules: just pick 1 and explain why.
I’ve been playing since the NES and despite being from a low income family I had the luck of being able to play and own many consoles over the 3 decades of my life, plus some pc.
If you ask me right now? Resident Evil 4 (2005).
A before and after in gaming, to this day still extremely fun to play even for casuals but 20 years ago it was THE masterpiece. And everyone took notice of it, everyone played it, even players that didn’t cared about resident evil. The gameplay was so good that it got photocopied by everyone right after in the action genre.
Arguably the last big innovator in videogames minus Minecraft and… PUBG (Fortnite did it better I know).
Try to NOT pick your favourite game, that’s a different thing.
It’s funny how the games that shaped our personal childhood shaped that belief… Holy shit the first catacomb game was a shitty gauntlet game. Cool history buddy down the rabbit hole.
I’ll still play doom from time to time - so it’s not history for me (similar status to pacman , tetris a few other old games)
I haven’t played cat abyss or wolfenstein since, well, since about 1993.
I dont play quake or duke nukem3d either.
