McDon: I'm worried about Numen mainly, don't want to waste time on a dl that big only to find it's crap.
I might get Freedom Fall, Smash Cat and Aeon Command.
Dynamite Jack looks eerily similar to Monaco...
I've played Numen. It's not a great game but I wouldn't say its a bad one. Feels like a single-player MMORPG. I paid $7.50 for it shortly after it was released, and put about 30 hours of gameplay into it (about 1.5 playthroughs.) I don't regret it, though obviously better games could have been bought for that money. For $0.75, it's not an issue.
Be advised, the "tutorial" section in the very beginning that you do prior to selecting a class is rather boring. Afterwards it gets better.
