Can't decide which one of these to play now. Help please :D

Play Serious Sam Classic: The Second Encounter :D

just dont start with black ops leave that to the end or dont even play

If you haven't finished it yet, I force you (with sweaty hugs) to play Half-Life 2 ;)

Portal

Leave Skyrim for last. That'll take a large chunk of your time and it's fairly enjoyable.

Serious Sam wouldn't be a bad starting pick.

portal

Half-Life 2 or Portal

Sit on your soft sofa and play Skyrim.

How come you haven't finished HL2 yet? STOP WASTING YOUR GODDAMN TIME.

Well.. starting off with Half-Life 2. Now, to decide what to play after Half-Life 2.

Half Life 2

begin with a meh-game (need for speed), then play a good game (serious sam) and in the late hours portal.

Half life is for the "mmm, got to checkitout" moment

In between (when bored) play casual, the ship and AAAAAAAAAAAAAAAAAAAAAAAA, flatout (fat princess?)

Skyrim is for when you have a bigload of time

The rest isn't play-worthy.

Portal and/or Fat Princess

Play Skyrim, you will emerge in a few days wondering where all that time has gone.

Portal. You've never truly sampled a slice of gaming excellence until you've played portal.
