I think for me it is WVM. I used to replay that game a lot, it's one of the very few games I have played all the way through more than once. At one point the dev told me I might know more about his game than he did. I know the updates are slow, but it is still one of my favorites.
Never went back to the xxx games I passed once. Too low quality. But I have returned to Heroes of Might and Magic III many times in a quarter of a century.
High on life was superrr weird, the soundtrack was so off-putting and had so many strange noises. It got to the point where it was giving me a headache and just made me stop playing the game
