Now that Forza Motorsport 5 is dishing out realistic driving, it's time for the Xbox-exclusive series to swing back to open-world arcade racing: meet Forza Horizon 2. While the announcement at IGN doesn't show much (unless you really like box shots), it promises a few big upgrades for both Xbox 360 and Xbox One gamers, including a weather system that hasn't been in previous Forza titles. You'll also get an adaptation of Forza 5's Drivatar technology that should deliver slightly more authentic (read: mistake-prone) AI opponents based on your friends. Naturally, Xbox One players will get a visual upgrade at the same time. You'll have to wait until the fall to give Horizon 2 a spin, but we suspect that Microsoft and developer Playground Games will have more to say about it at E3 next week.
