How I remade Game™ in-
YOU FOOL!
How difficult is it to call it something like Toby Bird's Overground? Feels particularly silly on somewhere like Youtube, where if the video blows up it's likely any future hopes for your project will too (and this could happen at any arbitrary point in the future, though probably with a change of staff or just before a new competing title is about to be released).
That and I feel that at least a little plausible deniability (while matching the feel) would add to the "Hey, has anyone ever told you that you look like Tony Hawk?" joke.
