For some reaosn a lot of games seem attractive to me right now. Must be my mood. I'm kinda swinging toward the casual adventure genre because im finding simplicity really rewarding, but there are 2 things holding me back.

a) the vast amount of time they require + money. Because there are so many

b) ArmA 2 is out soon

Escape Rosecliff Island

This is a like a game for your grandad. Its really just a puzzle game, but i played the demo and somehow got hooked. Nice atmosphere.

Amazing Adventures Around The World

Same kinda shit like Rosecliff.

Penumbra

Looks simple, yet highly atmospheric. Scary too. Something to fuck up my mind.

The Longest Journey
http://store.steampowered.com/app/6310/
Looks kinda like Broken Sword, which i fell in love with back in the day.

Sherlock Holmes
http://store.steampowered.com/app/11040/
Looks like another point-click-absorb adventure.

Dracula Origin

The screenshots look really, really fuckin awesome. Kinda like Sherlock Holmes, but better.

I can give you advice on a few of those

- Penumbra: incredibly atmospheric adventure/puzzle/horror/shooter. Some parts of series are better than others, but overall still very good if you're into that sort of thing (like me). There was a steam sale for the entire series at 5€ a few weeks ago, sorry you missed it.

- Longest Journey: one of the best stories ever in gaming, probably. Dreamfall, its successor, is definitely worth playing too.

- Dracula Origin: neat game, if you don't pay over 5€ for it.
