I will mention only three of them, but there are few others.
It was and maybe still is the best samurai game for me. I remember liking the world of this game quite a lot: the towns were soo detailed, there were soo many activities to do, and people to meet depending on the time (there was a day night cycle and if i remember correctly week cycle also), the music was incredible, also the combat system was great for the time. (it's probably the aspect that aged worse though). I've never finished unfortunately cause the game was not localized in my language, so i had to go with english and french, at the time i was weak on both. I'd love to replay it but i don't have an old TV to connect my PS2 Slim. (assuming it is still working)
The Sims 2: Castaway (The Sims 2: Island in my country)
I spent soo much time playing this game. Instead of being the classic Sims experience, you had to create a group of Sims and basically their plane crashed into a small archipelago, so you had to survive in those wild islands. The game had an insane variety of resources you could gather and very appropriate for an exotic island, and you had to craft everything: your shelter, your clothes, your tools, and the Maslow hierarchy of needs was still there: so you had to eat, sleep, pee, socialize,... in many ways it was Minecraft x The Sims before Minecraft even existed! Not only that but the game was structure in a way that invited the player to explore the other islands, there was a story to complete, several secrets to discover, learning new things, hunting new animals, seeding different plants,...
Even though it wasn't as polished as the mainline The Sims 2 i ended up loving it just as much, plus it came out few months after Season 3 of Lost, when the hype for that TV series of that was still over the moon (it started being crappy from Season 4) so i was very excited about a Lost videogame using The Sims gameplay. I believe i was among the first to finish this game, since i was throwing advices in the official forum.
I was a little disappointed when i found out where the big treasure was hidden: it wasn't a great loot. After that i built a legit house in the second island, but there wasn't much else to do unfortunately.
Dungeons and Dragons: Eye of the Beholder on GBA
Finished 2-3 times (so probably i played it for 35-40 hours), it was my first 1st person dungeon crawler and i liked it because of that (plus the combination of handheld + dungeon crawler works so beautifully in my opinion). Looking back i can see why it was reviewed poorly: the combat field and the chara design in battle was extremely simplistic, it had permadeath which affects literally everyone, and obviously your starting crew was much stronger than some random you could find in a tavern.
Ironically i believe this is still the only first person dungeon crawler i played, i'm waiting for a great one (just downloaded Labyrinth of Refrain demo but honestly i'm hoping for a great new Etrian Odyssey on Switch)
