I started playing the DW games when DW 1 first me out, 2 was awesome, 3 was epic, the original DQ 5 sucked(the remake for the DS is awesome though, DQ 6 is epic(the remake sucks though, so just use a translated rom of the original), DW 7 is the best game in the main series, and DQ 8 is a utter POS(and everyone involved in the development of such, should be executed). DWM 1 was awesome, DWM 2 is still the best monster capture/training game ever made, and the Torneko games were awesome as well.
I haven'y played 9 yet, because I'm too scared to, 8 was a POS, DQM Joker is the worst game ever created, and the game that was originally meant to be released as DQ 9, wasn't even a RPG(It's the FF series all over again, except at a much faster pace to ruin), so there's a lot to be scared of.
Everything Square touches gets ruined.
