I do not buy games. Period. I don't pirate them either.
Plenty of free games out there! Sometimes free demos are enough for games like halo, half-life 2, (sorry if I'm talking about old demos, I don't even bother with most new games anymore because even the demos are DRM'd up the wazoo). Freeplay MMOs like Runes of Magic and Allods keep me pretty well entertained after serious pointless grinding on an MMO like Anarchy Online. However! The point being is they are not only free of DRM they are free of cash outlay! No way am I about to risk my system with some DRM'd game that I may or may not like and risk my whole system on it. And pay cash for it beforehand.
The whole commercial game industry (well most of it anyway) is snake oil sales. They have quickly reached a point just slightly better than used car salesmen or the riaa. Feck it, stick to (real) indy games and/or play only the free games. If they lower the DRM bar later have we won? No, the game is still full of DRM bullshyte.
Anyway, apologies for the ramble. I hope you get what I'm after here (and no I'm not new here, but damn I bet any replies will make me feel like it)...
Soooo many free games to explore out there, I don't get why people bother with DRM shyte. Keep up with the Joneses? Not if it means compromising my system :P
