Is minecraft the same on the Xbox as it is on the PC?

I love watching Tobuscus play it on the PC it looks really fun.

The Xbox 360 version doesn't support as large of a world and also doesn't allow you to add arbitrary mods.

No. It's not as robust and the map is significantly smaller.

My son has Minecraft on both PC and Xbox. He says they are exactly the same only on the Xbox you have to use the controller instead of the keyboard and mouse of course.

The maps are incredibly small. You can walk from one side to another in about 8 minutes or so. And no mods. I'd wait until next gen minecraft if you don't have a good pc to play on. (minecraft is coming out for the PS4 and Xbox One)
