Doesn't matter what game it is, there will always be people that don't own it. Create what you wish.

I admit to owning each of the games listed (though only have the base game for Titan Quest).

I own Titan Quest, Sonic Racing, all those HL2s. I'm not sure about bundle games ^^

I don't own any of these games

Use this Clicky on S.Gift group and wait a few days
Good Luck!
and happy birthday!

It really doesn't matter, there will always be someone that will not have the game and will be really happy in case of winning it. :)

I only have Sonic RT out of those.
(and would only be interested in HL2E2)

I only own Titan Quest. Would love to win the Gold Edition to get the DLC.

Only missing Sonic Racing, and I'm not particularly interested in that. On the other hand, I don't know what's in the "some bundle games"..

I don't have any of those.

Give away whatever you want of those. From what I've seen, there are a lot of folks on this site that want each of 'em.
As for what I own, I have all of 'em except for Sonic Racing, and have half of the Titan Quest Gold package.

And happy birthday! ^_^

Go with sonic racing.

Happy birthday. Anyway if you want create giveaway I suggest create what you want. If you care about price of it, exclude all games from bundle list. That's all. Who care if someone have it or not. You are offering something to everyone for free and it is the point.

I don't have HL2: EP1 so I would appreciate that.
