I'll like or unlike ARPG its up to...
1. Camera : If they can't make a good camera view it'll ruin gameplay and intention to play it.
2. Storyline : Not too light and not too much complicate ,if the story just tell you "go out and kill that evil untill no more of'em" or " You're my son and my father was a king ,and he got a jewel in his mace ,and that mace hide under his tomb.Which his tomb bla bla bla".This'll decrease my willing to play for 10-20%(and maybe more if it really bad).
3. Variety : You need more than only 1 class and only 1 weapon to kill bosses ,i love to see new weapons and use it.Equip with best of the best armors which crafted with latest monster that i just kill.
4. AI : Ah ,please neither make enemy nor friendly units became some thing like a stand-still polygons or runing around try not to find some cover when they shoot to'em.
5. Bugs : in some ARPG ,only few bugs can destroy a game(for example ,you can not safe game or you can not pass this way if you didn't get that item ,and you can not go back to get it now.)
6. Environment : i need more than only fight in the same tunnel in every levels.Desert ,forest ,swamp etc. bring it on! i want them all.
Ps. Oh , i just noticed that someone already give a list like me when finish typing :p
