Pausing on your online profile isn't a problem, the major difference is that the save game is on their servers, and so can't be edited.

The game is funded and they have QA for the majority of bug finding, BXP seem mostly after feedback. They iterate a lot on the game so knowing what people like and don't like is important. So is knowing what features people really want, how they find the UI, what leveling feels like etc. BonusXP read this forum and the steam community one but have been much quieter replying to posts, they're up to their eyeballs in work trying to ship both this and The Incorruptibles.

The community is rather small right now so you aren't expected to have done multiplayer, and you don't have to go all in depth on it.
