Shin Megami Tensei
Tales of series.
Number five is kind of hard to choose. Every series I chose the series have been going down hill. Breath of Fire. Amazing, but the series is dead aside from a cell phone game no one wants. Mega Man. I can't remember when the last truly great Mega Man games was released, and yes Mega Man 9/10 are garbage imo. Armored Core last released with Verdict Day and Armored Core 5 which are easily the worst in the series. Not sure if the series is dead or if they'll release another crappy game to try and cater to the casual audience. *edit* I didn't even think of Resident Evil with how bad the recent games have been, that's another to add to the list.
