It is a fun game however there are a few drawbacks. Once you get to a certain point on tiers don't plan on getting anyplace fast or at all if you don't spend. I cant seem to get out of the 30s. Also no matter what you do the computer/other players always seem to target just you. Its a massive frustration when trying to place high enough on the events to gain tiers. Some of these tier groups for races won't allow you to score higher so you will lose tiers because the game cheats you out of it.
