Aladdin for the SNES when I was around 5 or so! But tbf, I used a cheat code to get past the lava level bc it was.... hard. So if that doesn't count, then it was Pokemon Crystal, around the age of 7. (I'd actually played Yellow first, but I never got very far, and only went back and replayed it after beating Crystal.)
It was a Seaworld game called Shamu's Deep Sea Adventures. Yeah. Real amazing stuff. You get to battle Poseidon at the end so that's something I guess. I had a weird obsession with that game for a while for some reason.
If by completed, you mean just finish the main story, then probably Pokemon Sapphire. If you mean completely 100% Midnight Club 3: Dub Edition on the PSP.
If I remember correctly,Advanced Dungeons & Dragons for the Intellivision console was the first video game I played all the way to the end.Of course,it was nothing like the actual book-based Dungeons & Dragons but it was still a lot of fun.
omg i remember the littlest pet shop games. i think the first ever game i completed was one of the charm girls club ds games (i was so upset that the sleepover one was a wii game only lmao)
It took everything out of lil' child me to complete that game, so many moments of horror that I'd just scratched my ds screen beyond repair, but... I completed it, before I ever bothered to complete any other game.
First game I beat was Banjo-Tooie, which was also the first game I owned. It took forever to actually beat (since games are hard as a kid, lol), but it definitely helped to solidify my love of video games.
The first game that I can recall beating was Spongebob Squarepants: Revenge of the Flying Dutchman on PS2. That was probably when I was about 6-7 years old. I've gone back and played it a few times recently, and I realized now that the difficulty is really low so I'm not surprised that I beat it, but I have a lot of fond memories with that game
Either a Gameboy color, or PS1 game.
Probably Pokemon Silver, or Rayman 2 The Great Escape, or Lego Racers, or Tekken 1, or Bomberman Party.
Or one of the games on one of those gameboy color 51 games cartridges lol.
It's hard to say, it's been over two decades since then.
