Heh, great Idea! There should be acheivements for this :P Like, Reach Level 100, or beat (a boss) Which should happen at level 50? New armor/weapons every 10 levels weould be nice, new monsters every level :P And the bonus's don't work for me :\ A shop would be nice, you could BUY the new armor/weapons. Buy x2 exp for ___mins maybe? Anyways I like it, please update :P
Its fun, needs acheivements though. No im not whining :P Just giving my opinion. Another idea of mine would be to but vehicles you can drive into it? Like plane wars, pure tanks/army vehicles, space war (future campaign) and some in regular campaigns, but still make there a normal with none. Those are just my ideas though :P
