Doesn't matter how good the previous sales are, if they weren't enough to self-fund a new title and they couldn't get anyone else to pick them up for a new one for whatever reason, there's not much that can be done. :(
Yeah I love Titan Quest. I'm now sad because they're probably not going to ever fix up the rubber-banding performance issues that Immortal Throne has. :(
It's not unplayable and for the most part the game runs fine, but the slow-down-then-speed-up can be annoying.
