Paper Mario N64, Paper Mario TTYD Gamecube, and the first Mario Luigi are probably the only good ones (TTYD especially bein great) so hopefully Paper Mario 3DS is good too.
Super Paper Mario, Mario and Luigi 2 and Bowser's Inside Story were all really boring. It's a shame because the latter two were similar to the first mario and luigi, and Super Paper Mario had a cool concept, but goddamn they were just so unbelievably boring. The 10 hours or so I played of Bowser's Inside Story felt like a slow tutorial.
