I don't think placing game related files in MyDocuments/Games/ annoys users, it's pretty much standard to put it there so why don't you do it? Each user can have it's own save games, skins and mods this way and it's easy accessible/mod-able.

However, for larger assets you do want to consider to share them amongst user accounts. I think you have two options:

• Users/Public/ isn't tied to a specific account and can be used for this.
• Store it locally like in a Data/Maps folder within your main game folder.

Apart from that, I think map data should in most cases not be all that large. Unless it are huge dynamic worlds you are talking about.
