So . . .
I just learned that what there is in beta is all of MegaTen ONLINE. Sure, there's demon collecting (but it needs REAL MONIEZ), some side-quests, you can make some cool weapons, kill some demons that only look different than demons from early game, and, yeah, "grind". Not to mention that the difficulty level was a disappointment. Defeating a boss on the first try is not something I would expect from my favourite series.
I think that I'll stick to the regular MegaTen games.
