Origins is a decent game, good fun on 4 player. Nice to see some good offline multiplayer.
Worms is a disappointment lately, Open warfare 1 and 2 on the DS/PSP were the worst Worms games created, multiplayer just never worked, out of sync all the time. Worms Reloaded and Ultimate Mayhem both aren't as good as what they should have been.
My favs are Worms Armageddon for 2D and Worms 4 for 3D. Ultimate Mayhem seems to be glitchy, so I'm not prepared to spend £10 on it.
I'd rather just stick with Worms 4.
