The test results you have selected are very old and may not represent the current state of Wine.

What works
Installs, and games (tested a few) can be run. I tested a few games and some of them needed some native dlls to get them running due to bugs in wine (quartz, oleaut32).
Also, some games needed Windows media player installed (solved by winetricks wmp9)
But that depends on the game, the XNA framework 3.0 itsself installs and can be used apparently quite fine.
