The amount of Codexer's praising BG2 is sad. It's a dogshit game that completely misunderstands what made the first game so great. I've replayed Baldur's Gate a solid five times starting from when I first joined the Codex, and it has been excellent every time. I've tried playing BG2 twice and both times I quit after only a few hours. As hilarious as it is for me to cite this article, Lilura really did a fantastic job at breaking down many of the problems that BG2 has.

Between FO, Arcanum, and PS:T, PS:T easily takes the cake. Arcanum is simply a broken game and any potential that might be gleaned from it by those who have the patience and know-how to get the game working is not enough to carry it to the top of this list (I'd argue it's not even enough to qualify Arcanum as a good game tbh). Whatever you want to say about Fallout, it has simply been outdone, with multiple games coming out that have superior combat, world building, and writing, amongst other things. PS:T has left the biggest impact, and it has the best first-time experience of these three games. It has very little replayability, but that shouldn't be a strike against it.
