Web and desktop programming, a few common easy questions.

Thank you for attention!

Let's get a final answer:

-not so much,

-cuz there is a limit for what u can get with web and what u can get with a real 3d engine/card

What does "not so much" mean? I wanna make 2d graphic games and may be 3d in the future using clean language, not engines.

I don't wanna make websites or forums, i wanna make pretty cool games.

What should i choose finally? WEB (JavaScript, ASP.net..) or Desktop (C# Windows Forms)?

Is it true that web is for websites and simple pages, but not for serious games that i wanna make.

I wanna make for web, because it is cross platform, but is it possible?

Please help with the final answer, because i have read so much, but didn't find what i need for.
