Lycanthrope posted a link to this thread, and I quickly skimmed it. My thoughts:
I would not buy a new game sight unseen, unless I trust the development house. I like RPG's, so I tend to buy BioWare games. Even so, it took a friend of mine months to convince me to even look at Mass Effect, because of all the DRM EA had put into it. I liked the game and played ME2 as well. It took a long time for me to buy DA:O for the first time, due to exactly the same reason. I only bought it 2 months ago, and only because EA had a huge special running on it.
I bought Sins of a Solar Empire a long time ago, based on a demo version of the game. Without that I would never have even looked at the game. Yes, there were reviews, but I purchase perhaps 1 game every 2 or 3 months, so stay with the development houses I know. I ended up loving the game, and buying all the add-ons. And I started buying a few more games via Impulse.
Speaking of SoaSE (
http://en.wikipedia.org/wiki/Sins_of_a_Solar_Empire) - Stardock has said that they won't put any DRM on it, and they didn't. You can copy the game freely for your friends in a LAN environment, but you need Impulse to download updates. As such, anyone can buy the game. Here in SA it was on the shelves at Look and Listen for less than a week "Because people don't buy such games". Now, for a game with no protection whatsoever, it sold over 500,000 copies, with 200,000 in the first week of release. So, does lack of DRM ensure that your games will be pirated and you won't make a profit on it?
