Even if you take into consideration the DRMed games, I still don't consider the bundle worthwhile. I checked out the Yogcast bundles from the previous two years, and they contained maybe 2-3 games, that I really wanted. The rest were worthless games I'll never play or extra crap, like vouchers and skins.
Don't get me wrong, it's great that they dedicate a whole month of their time to charity, and the developers/publishers giving away their work free, also deserve to be praised. But when it comes to value, the bundle isn't worth it.
About Guild Wars, Celton88, how do you find the game? I know it's an MMO, but do you find that you can complete the content alone or are you tied to other players? If the game could function in single player, when the servers eventually get shut down, I could add it to my wishlist. Who knows, maybe I'll live long enough to play it.
I know that the game and its expansions have been discounted appropriately(75%-80%) on STEAM, so it might not be worth getting the bundle just for the GW expansions.
