Decided to post here since the game specific forums seems a bit dead.

This might be a dumb question since it clearly states Windows 7 +, but maybe someone has tried this.
Will this game run on Windows Vista despite not being mentioned in the system requirements? Thanks.

Hard to tell, I don't have the game or Vista. The game was released on 2011 and Vista was pretty much dead after W7, yet it may be compatible.
Now the real question, why are you using Vista? Somebody is forcing you? You are kidnapped? XP

Vista should be fine I think.

The year where XP starts having trouble launching games seems to be around those released in late 2012 and on. Vista should have a few more years on top of that.

A LEGO related example: Lego Batman 1 and 2 worked on Windows XP, 3 did not. Seeing as Clone Wars was released in 2011 and Lego Batman in 2012, my bet would be on that it'd work on Vista, but can't guarantee it.

At worst, you can try and refund if it does not.
