Sorry to bump, just saw this thread, pitching my opinion.
Falcon: Bought
Opinion: Neutral. I purchased the Falcon a while back and at the time I loved it. I played portal and half-life 2 and was thoroughly entertained by the experience. After about 2 weeks of playing offline games, I felt that I was ready to start to get into my competitive TF2 play styles that I previously had. For about 10 hours of play time, I was frustrated, getting dominated by almost everyone, and just plain out hating everything to do with the Falcon. I drudged through this "getting used to" period and started to improve dramatically. Eventually my skill capped off, but it was far below then my skill with my mouse. I was forced to lean away from demoman, soldier, and spy and move more towards scout, heavy, and medic. The game overall was more fun from the start, but when I play, having fun is dominating or at least playing above average, which made the game very frustrating to veer away from my domination classes and move to new, unfamiliar classes. To people interested in getting the Falcon, I purchased it on-sale for about $100 and I would say it is worth that price. Anything more expensive then this seems too pricey. To players that are not competitive, don't care about their rank, and just play to goof around and have fun, this item is a great idea. It makes the game more fun, but lowers your skill (from my personal experience). To players that are competitive and constantly check their rank and get frustrated when doing bad, you will probably not enjoy this to the full extent, since it seems to take an extremely long time to get skilled with it.
All in all, competitive players should stay away from this unless they are willing to suck for a while. Overall, I would recommend this to any avid gamer though, since it does make any old, boring game interesting again.
