I'm the original poster of this dumb thread.
And I'm gonna answer my own question again, 2 years later. Worms Ultimate Mayhem is one of my favorite Worms games, I liked the cutscenes, loved the Worms themselves and enjoy destroying all my enemies, in 3D! But I can see why they are viewed down upon by some Worms fans. Something just doesn't feel right when playing Worms Ultimate Mayhem. I think it's just because at this point I've played more 2D Worms than 3D Worms. Like the game works, it's actually fun, but it just still doesn't feel right.
There we go. I might at one point finish Worms Forts: Under Seige.
