My point was 3DS does have the controls for it.

I guess the big draw in FPS games these days is the online multiplayer and, despite being quite capable in games like Mario Kart 7, it would drop the ball in the FPS department. Even Resistance on Vita was shitty online and the campaign was subpar. An FPS on 3DS by todays standards would be considered garbage.

It's all relative when you're talking about the processing power of older hardware - at the time those reasonably powerful gaming machines able to support the sort of games devs wanted to make and that publishers want to release and that customers wanted to buy. Though they may not be in direct competition, the 3DS is much less powerful than even PS360 and as the genre has expanded in scope, so devs have required more powerful hardware. This is why PCs had larger player counts per match in online Battlefield compared to the PS360 versions. Of course, that dosen't actually stop there being FPS on 3DS, it isn't a technical impossibility, but it would be a significant retrograde step which appeals less to consumers who would rather have those experiences on a home console, leading to lower potential sales which makes devs+pubs more reluctant to put them out in the first place

killzone for vita has quite good MP not sure how a 3ds MP would work, probably better than DS

I still haven't bought it yet.  :(

Resistance was horrible, though.  In all honesty, I liked the single player campaign a lot--for a portable--but even I could tell it was behind the times.  I have heard great things about Killzone on the Vita so I'll get my hands on that when there's a lull in my portable gaming.  The problem with that is, whenever I play online, I'll be home with my own Wi-Fi.  If I'm home with my Wi-Fi, I'm home with my PS3/360/Wii U!  I'd just play one of those.

The closest I've played on 3DS was the online in Kid Icarus Uprising and I hated that experience, too. 

Two very big reasons.

1. There is not second analog stick which is now the standard.
2. Big western devs are really the only ones who make them and they won't go near Nintendo systems.

However, there is supposed to be one in development by renegade kid.

Doom didn't have vertical aiming...no need of an analog stick then.

They must keeping all of them in Australia. For anecdote, I know about 25 friends that have 3DSs, and only one friend has it because MonHun. The rest do not know it exists. I'd probably get one, but I know have a reason to yet.

alot of people feel the way you do which is why we dont see alot of FPSs on portable. Sometimes im on my college campus and use their wifi and fortuanatly for KZ on Vita it is diffterent enough from the console KZ that the online could stand on its own. It doesnt feel like a mini version of the console online. otherwise i would probably never play it.

Cheap shot.

Install base doesn't always guarantee software sales. If you think a multiplatform FPS would sell better on the 3DS than the Vita, then I don't know what to say.
