@ Wombat457 :-
Hallo.....and to the Linux & Unix sub-forum here at BC.
I'll second the recommendation for Mint. While it's not one I use myself - I'm something of a rebel, and have been using a featherweight distro called "Puppy" Linux for the best part of a decade - many Windows 'refugees' find Mint easy to get on with, because it's not THAT different to Windows in terms of looks and operation. It's also very popular, and has massive community support.
Re : Flight Simulators. While I can't help with regard to your existing installations, I would suggest taking a look at this:-
Flightgear Flight Simulator
I've played around with it a bit myself, and I'm quite impressed with what I've seen. I've not got serious with it; my forte is packaging/re-packaging for the Puppy community, but it's very easy to get up-and-running, so should be fine in the bigger, more mainstream distros (of which Mint is one).
Just a suggestion. As an "alternative", it IS very good.
Your biggest hurdle will be realising that you can't just simply 'install'/run Windows programs under Linux without a fair bit of effort.......but the Linux community has very impressive, and highly usable equivalents to anything you can do in Windows. You'll find a lot of strange names, but don't let that put you off; every Linux distro has big repositories of 1000s of curated, maintained & security-checked apps/programs built just FOR that distro. There's no need to go searching around the web to find software; this is one of Linux's biggest strengths, and the sheer amount of stuff available for free is quite staggering to those not "in the know".
Don't hesitate to ask questions.....even those that may appear "stupid". The only "stupid" question, at the end of the day, is the one you DON'T ask!
Mike.
