As a newb to the scene, I can understand frustration with long awaited bug fixes and refinement request. And still, I must say for the fifteen bucks I paid for the steam version of season 2, the amount of fun I've had with TPA has been remarkable. Aside from ASK Homeworks Zaccaria package for iOS, I can't think of a time when I've ever purchased so much enjoyment for so little in a video game package. Also - the new dx11 lighting seems a major improvement vibe wise over dx9. I'm really happy with TPA.
My experience as well.
