Playing around with the beta myself and I can't seem to get in any road vehicles? I can get in boats and the helicopter but not any cars. Ok I managed to get into Mr Picking's red speedster ONCE but most of the time no buttons work at all. So it's just glitchy.
Also no icons show up when you're next to an NPC, vehicle, or building, to tell you when you can talk to them/drive them/go inside.
In the beta, Pepper often (but not always) plays an animation where he dips his toe into the water before he starts swimming. If you stop holding directional keys while this animation plays he won't start swimming once it finishes, like it's supposed to give you a chance to change your mind about swimming. I can't get this to happen on retail.
And zooming the camera all the way in on Pepper while standing still does... Bad things. (This happened while near the party house.)
At the front end, in retail the options menu text is "Options Menu". In beta it's just "Options". The beta also has different default audio levels than retail, and retail has vibration turned off by default, but on by default in beta. Different text in the screen offset menu too, and while starting a new game without a memory card.
Camera starts in a different position after the first cutscene with the Infomaniac.
In the infocenter, if you run all the way to the back wall and hold down in beta, Pepper slides along slowly. In retail he doesn't.
GOOD DAY MASTER PICKINGS (beta on the right, games aren't perfectly synced but oh well)
When leaving the infocenter in the beta, the camera starts in some other default position and rapidly whooshes over to the infocenter to view Pepper.
Here's a video of the beta from 2014 that currently has nearly 49000 views, with nobody even really realizing it's a beta
You can swim through boats on the beta.
I just tried calling the Infomaniac and he DID point to the objective... But only after I pressed the button a second time while he was already talking to me. Odd.
Sadly you can't drive vehicles off the edge of the bridge like on PC, they just hit the edge and spin around. There are some rendering bugs with pieces disappearing at certain angles though, and if you walk up underneath it you just phase through it to the top (if you do that on PC you clip through the island and end up walking on water).
Beta front end has no grass on top of space mountain, different road on space mountain, and no stairs at the skate park (but only in the front end):
Credits are mostly the same but there's some minor differences:
Including this rather amusing flub(?) in the retail game where the Testers section has somehow become... David Lane:
The floating radio is there even before the radio station is destroyed:
And the bug with the skateboard seems to happen whenever Pepper's state is changed during the animation where he puts the skateboard away... Talking to an NPC, sliding down a hill, etc.
