...so okay. I THINK the Impulse version of SF4 is GOO-only. So that's good.
As for Arkham, it sounds like SecuROM's only there for disc check (which falls in my "stupid but acceptable" category for DRM), but the game, by default, runs in online mode and associates your saves with a Games for Windows Live account. I've heard conflicting reports as to whether you have to actually be online to access your save files. Apparently there's an offline mode; I haven't been able to determine whether that's a simple flag you can set in your options or if it requires something more arcane and obnoxious like disconnecting from the network or blocking the program in your firewall.
And in not-DRM-but-still-bullshit news, apparently the only gamepad it supports out of the box is the Xbox Live controller. Now, given that there is a universal HID driver, and that it would be trivially fucking simple to add a "configure joystick" menu option, I would definitely say this points to MS being up to its old tricks and saying "If you want compatibility with the software EVERYONE IS USING, you need to support a less-popular one of our products." As I recall, that's what got the courts to...I don't know, my memory's hazy. Bake them a delicious pie? I'm pretty sure it was a pie. It certainly wasn't any kind of punishment or deterrent, or MS would have stopped doing it afterward.
So, Arkham drops another rung on my "things I would like to buy" list, and an Xbox controller gets consigned to my "things I will never buy, because FUCK Microsoft" list.
(Yes, it's possible to replace some config files and get a Cordless Rumblepad 2 working with the game. But that's exactly my POINT -- it would have been TRIVIAL to bake generic gamepad support into the game, and they deliberately chose not to.)
