Well I bit the bullet and got Roblox. Other than Sonic Speed Sim I dunno what to do with it.
Good news though, I made an Avatar that doesn't look like a cross between a womans love toy and a rubix cube.
Lucky you. Since I only borrow my son's account, I wasn't allowed to change his rubix cube-like avatar, lol.
I only play this one other game, called "Word Bomb"(?) where we and some other people have to type any word based on two/three word that appear.
No same words allowed and the clock is ticking until the bomb explodes at some point when we're not fast enough to find the word.
