Stacking is tempting. I remember enjoying the demo long, long ago.
Aren't the Red Faction and Kane and Lynch games all FPS? Not my type.
Some reviews for those on the fence:
Stacking -- Really cool puzzle game that my wife and I played together. She loved it more than me, but finding games she enjoys is hard. Every puzzle has something like 3-5 solutions (some of them quite tricky) and you feel impelled to figure them all out. Lovely game.
Red Faction Guerrilla is a pile of pure fun. Third person open world that's very destructible, even having cool challenges where you try to take down massive buildings with limited explosives. Destructibility is more fun and intense than any other game i've ever played -- you can have a blast swinging your hammer, taking out the support for a huge building full of enemies and watch it collapse without firing a single shot. Fun, fun, fun. It feels a tad 'budget' but the fun factor quickly eclipses that. Highly recommended.
Armageddon, however, was a sequel that didn't understand what made the first fun. Gone is open world. Destructibility still plays a part, but not in the same 'fun' way. I didn't finish it, and that's rare. Skip.
The other Red Faction game is a very skippable PSN game that's just a sort of car arena game.
I loved both Kane & Lynchs, but they're not for everyone? They are gritty 3rd person shooters with hard characters and harsh situations. The sequel has a unique look to it that I loved. They aren't perfect games, but they're worthwhile imo. I believe the first one has a demo. They feel quite a bit different from one another in some ways, but that's not really a criticism of either. Get em if they look good to you.
