Even though I won’t be able to access any of the DLCs?
Yeah. 2 is really great. Only problem is with low FPS (30 only). It stops me from playing it more.
It’s definitely worth playing if you’re a Horizon series fan, even if you’re just looking to bump up your Forza Rewards. I played it after H3 and H4 and still enjoyed it.
Positives:
The map is gorgeous. If they updated it, the scenery would be the best in the series. Enjoy the sunny Mediterranean from the “right” side of the road.
Forza Rewards will give you a great start on cars. I think I had 13 Million when I logged in first.
The racing is fun, even though it feels slightly diifferent.
Bucket Lists! - These were stripped out of FH4 and replaced with stories. There are 30 challenges to complete of varying difficulty. They are all pretty fun.
Negatives:
No/limited existing multiplayer This will make some achievements impossible.
Physics system I find to be a lot less forgiving then FH3/4. Small trees will stop your car in its tracks.
The map is less open. There will be sections in the middle of the map that you can’t get to due to side rails/fences. There are less nooks and crannies to explore.
Once you’re past the 2 Horizon Finales, its grindy to finish all the championships. The “road trip” mechanism makes completing everything a little more painful. Basically you have to drive to the 5 or 6 different regions of the map to start a new championship instead of fast travel.
The drivatars are just insane. Normally they drive wrecklessly on the road in FH3 and FH4, but you’ll see them cutting across fields, etc randomly.
what you mean by no/limited existing multiplayer? is it that bad? i really want to buy this game 
is it dead? @HaVoCStrikes?
No. There are people playing everyday.
The Xbox 360 version may have less people and fail to work online often, but the Xbox One version is fine.
I stand corrected! I didn’t notice the free roam and road trip options. I though all mutiplayer had to go through the car meet locations. Those always seem filled with drivatars that I know aren’t my actual friends playing the game.
You’ll love it. Best Horizon game, IMO. Lots to do and much more polished and complete than FH4.
But 30 FPS is still a show-stopper. I hope new Xbox could play those games properly. Horizon collection would be unbeatable stuff (1 to 4) in one remastered package. Because of licensing it will never happen.
