To be fair, I have seen trainers for Startcraft 2 and also C&C 4, regardless how horrible it maybe, and those too are indeed online games to, so clarify what you mean please. And as someone else said its an MMORPG... Hmm, not from what I can get outa the beta, it got a PvP aspect yes I agree there, but the campaign can be played both single and COOP, that to me says its not an MMO as such. Buth then again, I could be wrong ofcourse.
In any event I am looking forward to it as well and have preorded it from the EA store, and from there it says release date 27/04-2011
Well, it has PvP that uses your semi-SP characters. So anything that would aide your SP toons aids your MP toons (for they are the same).
C&C4 and Starcraft 2 had a great distinction between SP and MP, but there isn't such a big distinction in Darkspore.
While the game is not a MMORPG in the sense of UO, Everquest and WoW. It is very much like Guild Wars. With instanced battle zones where several players play.
And even during those instanced missions that are carried by a single-player (the supposed SP component), you are still playing online and can experience lag and other such things.
Cheating in this game's SP would be cheating in MP as well.
