[Help] VB.NET Games

[Fragma]

Hi, I want to start making more advanced game in VB.NET. So far I've only created simple games like Pong, Snake & Various mazes. I'm wanting to move onto creating a more complex game (Like the Gameboys Pokemon blue/red for example, only not as long). It will have levels, collectible items, various creatures to battle and computer opponents to play. I havn't got solid plan of what it will be like but I'm hoping to go down those lines. Now like I said, I only really know the basics of making games, So I was wondering if anybody could point me towards some good advanced tutorials that I can read up on. If you could share them with me that would be a great help thanks.
Also any tips or advice you could give will also be appreciated.

Thanks,
The Major
