Challenges
Challenges are great in the game. They can be buggy at times but its Early Access. Apart from that Challenges with Friends (Co-op Challenges) need to fixed if not changed. If 2 players participate in the challenge, 2 players need to do all the objectives/tasks in the challenge. I cant speak for everyone but personally, i dont the fact I can do the (10,000 points, 2,000 Spin Degrees, 3 Trick Line, etc) and all my friend or co-op partner has to is (180 Kickflip) and that counts as both of us completing the challenge. Both players should have to do the tasks for the challenge to be complete.
There's obviously other things like cosmetics, more tricks, more weather and dynamic elements but the game is in Early Access, like they will be all added once the game is officially out. We will get more variety in cosmetics, id assume dynamic elements will appear like weather or even Day & Night cycles. More tricks will obviously be added too but like I said, the Challenges are the biggest issue, theyre fun but need to change.
