I'm definitely down for some Too Human still. I'm in the middle of a move right now, and I would also like to try and re-acclimate myself somewhat to the games weirdo controls, but after that, I'm game.
As far as XCOM, basically my sell would be 3 fold:
1) Did you play and like the original XCOM, and if so, would you like a more streamlined, better made game?
2) Do you like turn based strategy?
3) Do you like SimCity-ish stuff?
Basically, it is an updated version of the old game, which is A LOT better. As a fan of the old game, I went back to it recently and found it almost unplayable in the amount (or rather lack thereof) of information they give you. I had trouble deciphering how to get out of the initial SCREEN. This is a lot more user friendly (but definitely still challenging). The SimCity part is really SimCity light, but still cool, as your base is underground and you have to choose where to excavate and consequently where to build new parts of the base (Psi labs to learn psionic abilities, foundry's for upgrades, workshops and labs for more engineers and scientists, hold cells for alien interrogations, etc...)
It's just a lot of fun if you're into any of the tactic style games (FF, Tactics Ogre, etc...although this isn't on a grid per se). The brutal difficulty only serves to help the dire plot in which humanity is surprised and outgunned. It works well I think.
I'd give it a shot if you're a turn based fan at all. If you aren't, or if you are bothered by dice rolls (every attack has a % in this so Twigg, avoid), then I'd definitely stay away.
