I'm brazilian and i must admit that there are some things that should be improved in physics crashes, but as the game is still in alpha, it's likely that they'll improve.
Greeting from Brazil, this game is in Alpha and there are big updates coming. Making a game like this in Brazil is very hard! Actually entrepreneurship in Brazil is not easy and the guys that are doing this game are very brave. The Idea and Scenario are pretty good and it started after the Brazilian Community created tons of mods for GTA SA, making GTA SA As Brazilian As Possible with those mods. I Want see this game in the next 4 years, it has a big potential! It is made by Betagames Group from Sao Paulo and it uses Unreal Engine 4
I've got to say, the suspension physics are really satisfying but the cars don't feel like they have weight to them like they fly easily like in this clip 0:27
There might be curb snapping, which should be removed. I don’t think there is deformation for things like the cabin or roof and doors, physics are weird, vehicles also NEED LODs (Levels of Detail) too, I think vehicles turn off when you exit based on viewing gameplay, instead there should be a option to leave cars running like in GTA IV. There also should be a option for a vehicle camera that centers itself on the vehicle, the current player centered vehicle camera is also bad as it is not a player centered camera, it is literally just a camera panned to the left a little bit to give cars a player centered feel, the problem is that this is also applied to bikes, which should have the same camera player centered or vehicle centered. I hope in the future these are fixed and we get a proper GTA Rival, maybe we can even mod the game in a future.
Do not buy yet, this is a pre-alpha version. Wait the game be completed, until now was 10 years (2-3 years payed) of development with many third party assets for just this.
