I REALLY hate the attitude of crying that a PSP/DS game is on a handheld rather than a console, especially given they're designed around portability or the DS's unique capabilities. If the small screen bugs you that badly then get a DSi XL and a PSP 2000/3000 with TV output, neither option is all that expensive now anyway. I understand if there's just one or two games you want, but if there's a TON then you're only doing yourself a disservice by ignoring handhelds, and frankly acting like that only exuberates the problem. Granted, an XBLA/PSN port might be easier to deal with than a retail release, BUT that's still more work for the publishers that they may not feasibly be able to do, especially on XBLA if they haven't gotten much published at retail, and sometimes those end up compromised anyway. Half Minute Hero just hit XBLA, but they completely ruined the extra modes by turning Evil Lord/Princess/Knight 30 from distinctive (albit short) gametypes to one level Hero 30-type stages.
Some of these games we're just lucky to get, it's better to roll with the punches and get them where you can. Also, they're right: getting the PS1 version of Tactics Ogre over the PSP version just so you don't have to play on the PSP would be a monumental mistake.
