I can say that any game that has to be connected to a server, just to play in single player mode, is one that I will never buy. I have played Blizzard's games a lot over the years, going way, way back, but if that's their new way of doing things, they'll never see another dime from me.
I haven't had a lot of time lately, but have been picking up the occasional old school game from GOG.com. Cheap, and there are some classics on there that I probably own somewhere, but are typically hard or impossible to get them running on modern hardware. GOG takes the work out of it for you. I can have more fun playing Syndicate than with most of the new stuff out there.
