For the review, this is one of those games that doesn't seem like it will be much fun, but six hours later you're still thinking, "OK, I'll just capture that planet and I'll go to bed." It uses space combat, ground combat, espionage, and diplomacy in the best mix of any game that I've ever played. Only espionage is optional -- you can't just brute force your way to victory. Gameplay has stood the test of time, even though the visuals are very dated and the controls are awkward for this era. On Windows 10 running as a non-privileged user, I did not have to do anything to get the graphics to work. If you have graphics issues, run in Windows 95 compatibility mode. You do not need to run as administrator. If you are suffering frequent crashes, it's because this game was never tested on multi-CPU/core systems. While Rebellion is running, ALT-TAB to the desktop. Bring up Task Manager (CTRL+ALT+DEL if you are running as an admin, otherwise press the Windows key, then type 'taskmgr.exe', right-click it in search results, then click "Run As Administrator). Find REBEXE.EXE on the Details tab. Right-click it and click "Set Affinity". In the dialog, uncheck <All Processors>, then check only CPU 0. OK all the way out, then switch back to Rebellion. Enjoy your crash-free game!
