Its weird the game will just not go into a race sometimes.. you will sit with other races in the staging area if you will, and it will just say waiting, no host shown, nothing. You can still type or talk to the other racers, but thats it..
I put it down and came back to it later, and all was well again. This has happened more than once and no amount of logging out, turning off the system. Leaving that game room and entering another fixes it. I know its a beta, but just saying for people that have not tried the beat yet.
The boost is used up really quick. You have some pretty good control over drifting, and it adds to the boost fairly quick. The game is faster than i thought, its just a matter at getting the boost, and hitting the arrows that speed you up.
Some people are really fast. They are either really good at using boost or know of some serious shortcuts. I can normally place pretty high, but just like Mario kart don't count anyone out. I was in first and second and almost to the end. There was a item launch just as I was making a jump... it slowed me down mid air and dropped me between the jump and landing... as I started to go I was stuck if you will between those and had to hit select to reset... which blows your cart up and starts you back on the track... needless to say I finished last because of that... my track times were the fastest for that race as well, which pissed me off. I was pulling laps faster than anyone else.
You can keep your items and gather more balls to upgrade the random item you are given. From what I can tell you can get up to 3 stages of the item and each is a bit different... now the risk you run is if you get hit with someone else's item, you lose yours. So holding out for the high upgrades you risk losing it all together. I have done that a few times.
Also your boost meter is the block (shield), as well as the sideswipe meter. Sideswipe took me a while to figure out. Its the right analog stick flicked one way or the other while next to another cart, left analog is steering. It uses boost, but bumps them pretty hard. It can throw them into a wall or really mess up a turn for them.
I see some of the faster players boosting while drifting, and I think thats the key. I think it may keep your boost meter even to do that (infinite), but I have not mastered it yet.
The one thing I don't like is the drifting function kind of locks you into one direction. If you hit x to jump and then turn say right, you can not drift back to the left at all. You need to hit x to jump and then land while holding left.. There have been many times I wanted to make a small correction before drifting into a corner, and drifted off the wrong way.
Overall I think the game is actually really good, and compared to some other betas I have read about, seems to function really well at this stage.
