GS 3 is stooopid, it's crackers.
If you enjoyed the first one ( or your kids) then this is a no brainer. My 16 and 11 year old are chuckling and lol ing right now to it.
You can now swim, drive cars and do loads more.
People who moan about bugs do not know the lore, it's part of the chaos.
I wouldn't pay more than £25 for it but it WILL make you smile so it all depends how much that is worth to you.
Enjoy the madness.
