What's the first game you remember finishing?

First game I remember finishing through would be A Link to the Past. I did warp flute to the end of SMB3 but I don't count that as a "first beat"

Final Fantasy Tactics, though SSBM was the first one I reached 100% on.

It was Stronghold crusaders. I played it on 2001 I remember.

I'm someone who never finishes games, but the first standalone game (not including text based games or MUDs) that I finished was Mafia II, and it was also played on OnLive as my PC couldnt handle it at the time.

Probably one of the old Harry Potter games for PC. Chamber of Secrets was my jam back in the day. I also liked Chibi-Robo on GameCube.

Probably Luigi's Mansion on Gamecube though I was a kid so I think I got my siblings to help me.

SpongeBob SqurePants: Battle for Bikini Bottom on PS2. I didn't have a memory card, so I would leave my console on for weeks and it would make my parents so mad lol.

Sonic Adventure DX: Director's Cut for Gamecube (2005-ish?)- I remember I had a one of those Prisma Guides for it too lmao. I don't honestly finish games too often.

First game I finished was Pokemon Emrald back then - to this day it is still my fav

Paper Mario. Gooooood times man. Final battle was impossible for my baby self
