I said this on the other thread, it's obvious they don't yet have the clout to go after big titles like GoT or GTA yet, and it would be a losing strategy for them to do so. Hence why they are going after battles they can win first.
Yeah, but not yet from Steam. Anyway the point is, people keep bringing up "why don't they go after GTA and GOT instead of fringe eroge" so, yeah, one - they have but it was a partial success at best - they aren't ready or able to make that leap YET.
