XNA or GameStudio?

Plus 3DGS is adding COM programming with A7, so its down to your programming skills, if you are good you could do lots more stuff with the engine.

Plus XNA is a framework and not a engine.

JCL is added a faster render for A7 if he keeps moving in this direction and keeps up with the latest hyped tech, 3DGS will be great and sell.

Though you can plug in the open-source standards like physX or newton. But these are engines too so i'm basicly telling you the same. Usually the game engine's are build on a framework (as 3dgs is build on directX). And as directX and XNA offer a variaty of features you can also take a rendering engine (like ogre) and add some other open source standards to build a engine.

But game engine's aren't needed to build a game. You can build it from scratch too with directX, but as doug said you will have to program a hell of a lot more. But the good side of that is that you can do everything exactly the way you want in stead of having to use the features of the engine builders

Intresting feedback thanks for the help. I still cannot decide cause XNA seems like it is going to get way more advanced and cool with 360 features but Gamestudio seems like I can actually use the tutorials cause I need better tutorials than the crappy XNA offcial ones

There are some tutorials on the web available:
http://www.thehazymind.com here you can find how to build your own XNA engine. I use it only for reference materials because i find it easier and better to do some of the stuff the other way but for beginners it's great

I have tried quite a lot of tutorials and I cannot get any of the code they tell you to put WORK! Not even the video tutorials they all suck I guess? Or they are just not specefic enough! Anyone got any links to some noob friendly ones for XNA?

DirectX and XNA will never turn theirselfs into engines, because they're just library's. The game engines are based on DirectX and XNA, and why do you think XNA is low level, many games on the xbox are written in XNA. Game engine's are just there to ease the programming, but they are still based on library's like XNA or directX, and if you're looking for flexibility it's better to write your own game engine, cause with other engine's you will encounter stuff that you would like to see differently or not at all

Game engines using XNA as their base have started popping up. Do a search over at Gamedev...there's at least two of them. There's also some Nintendo Wii support emerging, too. I saw an announcement for Wii support for some engine the other day, although I can't recall the one. IMHO, a Wii port of 3DGS would make sense given the inexpensive, more indie friendly costs associated with the behind-the-scenes crap. 360 I'm guessing would be a simpler port, but it's my understanding that kits are much more expensive.

yeah, though you can port XNA directly to your xbox360 with a subscription to the XNA creators club, though you can't use it commercially (they will if you apply it for a marketplace game though, they will have to like it off course or else you're done for )

Here's an XNA engine...they claim to be the first full development system using it. $249 and $99 licensing:

I recognize that one model...I have it on my drive somewhere. Anyway, it looks like a BSP engine with native support for FBX and X and of course C#.
