PORTAL

(Part of the "Orange Box")

Peer into the nearly perfect game concept.

19 levels of simple, clear, snarky, challenging, mind churning fun. Remember to think in 3 dimensions or this wonderful game will hurt your wittle head. Portal is massively underrated - play it and be transported. Play the entire game; it's worth it.

This is possibly the most perfectest game ever.
Note: if you get stuck on level 19, have a seat. I can say no more...

The alien races all have well defined quirks and enjoyable traits.

MASS EFFECT
Played it all the way through. Now I want to play it through again. Solid world building, GENUINELY compelling character moments, ethical choices and of course, plenty of ways to shoot at things. Patience and tenacity are constantly rewarded in this well conceived science fiction drama. Note: A few annoying quirks include many of the menu controls, the inability to upgrade the MAKO vehicle and the fact that you are locked into your 2 of 8 character away team for most of the missions.
