regarding the legality of breaking the sound barrier:
if i remember correctly there’s is an indirect general speedlimit, because any vehicle moving below a certain height is not allowed to go beyond 400 something kph. now this is intended for planes and helicopters and such, but afaik also applies to cars. therefore breaking the sound barrier, sadly, would be illegal. besides, i think breaking the sound barrier is limited to certain zones anyways.
i’m not trying to nitpick on the joke, but rather give supplementary information that may be interesting.
i think that with sone shenanigans you might be able to keep your game installations, but you would need two separate harddrives in your system and some tinkering which i doubt will be easy when it’s your first time touching linux. i have done such thing, but only among different linux installs, and with some linux sysadmin experience. if you got the drives and enjoy the tinkering, id recommend you do that, cuz worst case scenario is you gotta reinstall them which you’d have to do anyways if you didn’t try…
here is how id do it:
i think that all but the last step are pretty certain to work. the last one may cause you some trouble. note that it’ll probably only work with steam games.
