My personal favorite for the diy is the dragon's lair.plenty of room two bridges and and a tunnel leading to it. oh and i forgot about the already made ramp in there.
As you all may know, Codeglue has recently upgraded DIY Racer with new controls and a boost system. For me, the new control system makes it much easier to use. I have setup a DIY Racer course at our NA clubhouse (Your PS Home 2) for all to try it out. For a limited time, we will open the clubhouse to anyone who wishes to try it. Just send a club join request to Your Ps Home 2 (don't forget the spaces). You can join the clubhouse from any region. Clubs are limited to 32 so first come, first served. We will check the account as often as possible to process the requests. Please not that since this clubhouse is only used for special events, we will delete all members after this event in preparation for the next one. Here are some screen shots of the course : Also checkout the Showcase --->> CLICK HERE
