Not all sequels are good, oh ho ho not at all. But usualy if it has a strong multi-player, the previous game users switch to the new game because, well, it's the newest. Also, games update and change ALOT, not always for the better in some veiwer's eyes. What games for you have become obsolete or "upgraded" but you miss?
Mine is probably the start of TF2 without the upgrades or hats. Though it's true it adds more variation to the game, some of the items are so imbalanced one way or the other that they make the game a little too crazy or painful at times. Like when the other team is full of Demo's charging your team with swords and shields drawn, reducing your explosive damage and chopping your head off. And with the hats... well, some people take vanity very seriously ("My hat means I am superior!") and it was the spawn of Idle severs.
