Forza Guys, I want your opinion.

Would it be worthwhile to get Forza 4? I'm really late to the game, so the online portion probably wouldn't be worth it as most everyone has moved on to other games. What about Forza Horizon? Another board I'm on seems to have several people who are playing it and seem to like it.

Any thoughts?

A lot of people still play Forza 4, given activity I've seen on other forums. I haven't gotten Horizon yet but I'm not sure about it. I've heard people say it's great fun and they can't put it down, and I've heard others say they got bored with it quickly and it's a waste of money. I've not heard anything in between.

I still play FM4, and will be playing Horizon once I am allowed to open my Xmas present ($15 at walmart, woot).
The online lobbies are still full, and all the kiddies that were there just to crash have long departed, which is what I was waiting for. I've been driving around aimlessly, losing races, just to rack up miles on certain cars for the badges and achievements.
