For anything thats older like TibSun, RA1 etc - I recommend using a XP virtual machine (free from M$) if you have a computer that can handle it. Otherwise a second install or second PC with XP on it. I know, i know, its 15 years old but I never said use it for internet browsing - thats the only part that will get you in trouble. For compatibility with older games, it's still super useful.
