Sony and MS are no different.

It will be a long time before games on the console networks are as cheap as Steam, Google Play, Apple, etc etc.

The answer to your question is Wii U owners have nowhere else to go for games than the eShop.

So the games are basically exactly the same besides for some small graphic changes and analog controls?

That's a rip off and makes me not want to support them games then. Unless, they are exclusive or priced equally why buy them?
