average person on aoczone is clueless 1450 guy, and making this for vote is useless popularity contest
While most obviously lack the insight that you have in the games (which hopefully you will share more via commentary in future!), this is the only alternative that will minimize strife. If a select few players decide who was MVP, there will be naysayers going through all kinds of data to try and prove that the MVP is some other player altogether.
So yeah, it will probably end up being a popularity contest. But do remember that being low in gaming skill does not imply a feeble mind (and as it turns out, even the reverse is not true!).
