Cool thread!
AO: Hm... A mixture between the Monsaic Lines and Scrabania I'd say.
The Monsaic Lines because of the beautiful shades of green. And I like seeing all those chanting Mudokons and getting them stung by bees!
AE: Uh... I hate it when the wildlife ends on this game. I love Necrum because of the desert-like stuff and all that orange, eerie mist.
MO: The brewery to be level, I love making those Scrabs chase the Slig, and I love it when they turn and growl and you, it's just hilariousness!
SW: I didn't like this as much as the old games, but I did like the Sleg hunter mission. It was really hard for me, but I enjoyed it!
