"PSP looks much better [graphically] than 3DS"
Is that supposed to be PSP2 or what? I've only checked a few games on the 3DS, but subjectively the 3DS's screen and also graphics look superior to the PSP's offerings (not that it matters much to me. PSP and 3DS both have awesome graphics, better than I would ever have hoped for to have in portable machines) Of course PSP2 will look much better, but is it really that important?
"3DS is for casuals; like the DS"
... And the problem with that is? I'm a casual gamer since more than 25 years and have over 400 games for more than 20 systems on my shelves. But I'm OK that 15 year old guys who think gaming started in the middle of the 90s on the Playstation consider themselves hardcore and me a casual.
"Pilotwings is a minigame"
Pilotwings is a fun experience. If it's not your cup of tea, forget it and play something else. It's that easy. Some big action games can be beat in 4-6 hours. Can't they also be considered "mini" games in terms of length? It doesn't matter what type of game it is as long as you have fun with it.
"The 3DS line-up is almost completely made up of remakes"
Remakes are bound to happen on all consoles from now on. Just live with it and wait a few weeks, then original games will appear, too. If you don't like remakes, don't buy them. You may not believe it, but there are people who didn't play the original and might enjoy the remake. Yes, really, I didn't make that up...
"Steel Diver is a tech demo, and a bad one at that"
Does that sentence come from a person who played the finished game? No? Thought so. Point is moot. And I say it again, if you don't like it (or the genre), don't play it. Is that so hard to understand? (I for example won't buy it because it's just not my type of game, but I'm sure there will be people who love it.)
"3D is a gimmick, and will fail like 3DTV"
It's impossible to argue against prejudiced views like that. 3D isn't liked by everybody, but people who do like it won't start to hate it all of a sudden. I for example wasn't totally sold on the 3D feature, because my eyes can't see 3D very well it seems. I've tested 3D TVs in stores with the 3D glasses and hardly could make out the 3D. Another gripe was that the picture would get darker when you put the glasses on. With the 3DS the picture is always bright and looks really beautiful. And btw, the 3D can be turned off, so if you don't want to use it you don't have to. The games will work either way.
