With a lot of non-portable, non-Tales RPGs lately, I tend to lose interest just from playing demos or watching trailers--with Arc Rise Fantasia being the most recent victim of that, though I may still buy out of residual good will for the Symphonia people who are with it. If the game doesn't scream "buy me" right away, then I'm not buying, and so I never end up feeling like I'm wasting my time or money in the middle of playing. Sorry you do, 2DMention. :/
Of course, maybe I miss lots of good things because of my cautiousness, frugality, stupidity, or whatever one might want to call it. I don't know. But I do know that in the last twelve months I've been playing Etrian Odyssey II, TWEWY, Fire Emblem, Guadia Quest in Retro Game Challenge, Dragon Quest IV, Dragon Quest V, Chrono Trigger, Ogre Battle, Super Mario RPG, Secret of Mana, Star Ocean: Second Evolution, Pokemon Platinum, Tales of Symphonia: DotNW, and Tales of Vesperia.
And I also know that the only thing I can say after playing all those games is that I've never felt less burnt out on RPGs as a whole. Even on the horizon there are 7th Dragon (hopefully), Dragon Quest IX, Shining Force Feather, Mario & Luigi 3, and Tales of the Disco Swordsman--among others? Sign me up. In the most literal sense, all the best aspects of the past and present of RPGs have been combining to remind me of everything I ever loved about the genre and ever will. Try looking into some older RPGs, and maybe the elements that separate them from newer ones will remind you too.
