Back to what I said earlier, since my life is so exciting I've broken down the titles I have on Steam: extensively played/completed, moderately played, tried briefly and hope to revisit, tried briefly and hate, indie bundle purchase, and free (the latter two categories meaning it's fairly irrelevant how much I've played since I got them for nothing to next to nothing).

I think!), P.A.M., Puzzle Chronicles, Puzzle Kingdoms, Runespell Overture (thanks MHC!), Serious Sam First Encounter, Sol Survivor, Unstoppable Gorg, Zombie Shooter (thanks MHC!), Zombie Shooter 2 (thanks MHC!).
Haven't played at all: Just Cause 2 (when I finally get off my ass and upgrade to DX 10), Renegade Ops (same), Team Fortress Classic (came with the big HL1 bundle I bought).
So, there you go. Eyeballing it I'd say over half the games I have came as gifts, freebies, or from cheap indie bundles (where the average cost of the game was $1 or less). Another 40% or so I played pretty much to completion or spent significant amounts of time on (relative to the type of game/length). Only about ten or so have I bought outside of indie bundles/on their own where I ended up not really liking the game at all (and from looking at them I doubt I paid more than $20 total for the lot). Out of the indie bundle games I'd say about half I found worthwhile fun (some extremely good), and the other half I probably could have done without.
; sigh. To be fair a lot of that stuff is various bundles...
