Monster Hunter G isn't entirely a quick cash grab by Capcom as they work on Monster Hunter 3. Well, actually, it is, but it's a quick cash grab with online play, which seems a lot better. Monster Hunter G's online mode revolves around various quests given to players from their guild hall. They're about what we'd expect: kill this monster, get this item, etc. Groups of up to four can participate in the same quests, using equipment (traps, bombs) found within the quest to complete their objectives.
The game's quest-mode environments (or the real game) look much, much better than the in-town stuff we've seen, but MHG still looks exactly like the old Monster Hunter it is!
