I have really liked the Horizon Series, however eventually got bored with H3, as the overall "wheel feel" FFB and physics, mostly FFB, wasnt bad but..... (i guess spoiled by great feeling sim race games)
H4, feels like H3, but refined and polished, in just the right places! With a few nice changes/ seasons?
Mostly for me, the FFB feels much better and enjoyable, which is the main thing that will keep me. Fun to drive! Graphics are alittle better, and artwork and world design is a noticable step up. Maybe being in England helps - the world just looks more believable. This is the awesomeness of H4 to me, can have a great Simcade (maybe more on the "cade" side) rallycross race one minute, and do unreal crazy stuff, driving your car up the mountain and off the cliff, achieving some vertigo, the next. Or top speed on highway, then veer off into the woods (in cockpit view) and try to avoid all the big trees! lol
Anyway for me, the best arcade/simcade racer ever!!! BTW, old xbone, no 4k. still looks great!
in a few more days, when i finally finish downloading PC verision, LOL, i can comment on that
