which team made the gran turismo game for PSP?

Again, you're trying to use sales to determine what is a spinoff or main entry.  You can't do that.  Especially considering many early Mario games saw A LOT of their sales from bundling of the popular HW, which hurt Mario 64 sales in compariosn when N64 didn't sell so well.  And as far as gameplay, yes Sunshine was quite different, which is why I won't argue against it being a "spin-off."  Mario 64, on the other hand, has gameplay much like the original games.  The only differences (and there weren't really that many) only came about because of additions needed to be made to accommodate the transition to a fully explorable 3D world. 

Now, let's say next gen the next Nintendo console fails to sell close to what MS or Sony's next offerings sell.  Say Nintendo releases a new Mario that, for the most part, is just like SMBWii.  It obviously isn't going to sell as well as Mario's Wii offerings.  Will that make it a "spin-off" by default?  Of course not.  Which shows that your reinvisioning the history of what Nintendo made as a main entry vs. spinoff by sales is flawed.

For comparison, GoW GoS is a late gen PSP game where no other PSP game really comes close since it uses fixed camera angles it can use a little more juice it saves from having a more open world and free camera.  On the other hand you have 3DS running the MT Framework engine, higher poly count, more enemies, lighting engines, much better texture work, etc and it's rendering each image twice to give the 3D effect and this is coming out within the first few months of the 3DS' life... only slightly better... right...

It certainly looks better than any game on the PSP without a doubt, but it doent blow it away sadly. I would compare it as xbox to PS2. 

For the love of God people need to take off the nostalgia goggles... 

Nothing and I mean NOTHING last gen looked that good, hell it's like the people trying to say SMG looks like an Xbox game, it doesn't, these have been ranked some of the best and best looking Xbox titles... It DOES NOT stack up to the likes of RE5, hell they said the Wii couldn't run MT Framework for the longest time and it's stronger than the Xbox.  Please PSP is weaker than PS2 and 3DS is stronger than Xbox... and between PS2 and Xbox was a pretty big leap for most games especially if they were multiplat.

The leap from PS2 to X-box wasn't that big.  It is like the PSP to 3DS, yes it can pump out a few extra polygons, but the biggest difference is the AA and shadowing/lighting effects.  Though, honestly, the models (especially the zombies) and shadows weren't all that great in that vid you posted of RE:M, anyway.  And sorry, but it doesn't look as good as this:

Edit:  One other thing.  it's a misconception that the 3DS is taxed twice as hard because it has to render the same image twice.  The fact is, the game is only rendered once.  The in game cameras only has to capture the rendered scene twice, one at a slightly different angle than the other.  It would tax the 3DS less than split screen multiplayer, as that HAS to render the game twice to display different parts of the level at the same time.  Well, unless its a game where the whole level is rendered at the start of every level, which I doubt many do.  Just don't go thinking if someone made a game on the 3DS, sans the 3D, it would look twice as good as the games coming out for it now.

I remembered Actraiser 2 was beatiful and nothing this gen has matched it graphically.

Uh Doom 3 has bad textures like the rest of those Xbox games I showed off and their models aren't that great compared to today's standards which is what the 3DS is living up to....

I'm just going to stop replying to you now cause you're just so far gone that you're even posting videos that look better and thinking they do, not to mention they don't do more on a technical level, I'm guessing either you don't know what being superior on a technical level is or you're grounded so deeply against the 3DS it isn't even funny, and either way it makes any "disscussion" with you pretty much pointless on my end, since I'll post proof for it to only be rejected, while I'll still be open minded if someone could actually prove my point wrong. 

I assumed the rainbow on the outside of this thread stood for Tom Clancy's Rainbow Six.  Obviously, I'm in the wrong place.

*leaves thread*

What you said pretty much sums things up, my three favorite teams on Sonys payroll are Naughty Dog, Insomniac, and Sony Japan, and only one of those teams has even supported the PSP... and they supported the PSP with a port of a mainline PS1 title and some minigame collections, so other than the port I really didn't care they made games on the PSP cause they're not what I want to play.  

Out of all the titles Sonys outsouced the only game to come out better than the mainline was Resistence and I will swear by that game, but the console series is probably some of the worst FPS mechanics so it's not hard (seriously they need to put Insomniac on some new platformer IP rather than some new FPS IP, but this is getting away from the topic)

Basically I buy Nintendo handhelds cause I know Nintendos first party will support them with a slew of mainline and quality titles, on the PSP I waited till there was enough support from Square till I got it (Crisis Core and bought a star wars white PSP with it) since then I've looked into things from every genre, the pickings are rather slim for good original titles on the PSP that are designed with the handheld mentality, most of them are cut down console games, and that's simply not what I nor most people want on the go.  This isn't me slamming my PSP since I've been playing it more than my DS the past month (because of tactics ogre) it's that those games that get me away from my DS are few and far between and rarely ever come from Sony themselves.  

Then I see NGPs line up and it's again outsourced games attached to IPs I generally don't care for, Uncharted is the only one I do care for, but by the looks of that game it's built around the same idea of the GoW and R&C games on PSP, take assets from the mainline, color by numbers, do nothing new, and done! I don't want to play that, sorry, I'll wait for reviews on the launch lineup and probably wait till if/when a Monster Hunter or a Kingdom Hearts title hits the NGP, in the mean time I'll just play my Capcom games and Kingdom Hearts on my 3DS.
