Help me pick a game?

Fortix!

FTL?

Use a laptop with trackpad a lot myself. Portal is not too difficult with a keyboard/pad combo, but easiest are clicky things. FTL is fantastic, strategy games obviously (I like to play Civ). Games that use keyboard and no mouse are decent too...Binding of Isaac for example.

The Binding of Isaac is perfect :D

Deponia? Well actually I haven't played it, but I'd like to play it...

Braid?! just found out that i own it and its kinda interesting.

Adventures of Shuggy is nice game.

Binding of Isaac and Super Hexagon - keyboard only

Dwarf Fortress; No mouse required.

QWOP if you like a challenge.

binding of isaac and dynamite jack.

for burning some time i play civ 5

Castle crashers? :)

You don't have it in library but you could try the demo :)
