I recall pickup up Unreal in the store several times on several visits, putting it down, checking out the stats on it, when I found EPIC on it, I decided......uhm...yeh, but my computer wasnt up to specs, I eventually found a CPU that fit my system, and it ran...in 320x200 software mode, 200mhz cpu speed, no accelerated vidcard.
When I started the game, I was in the middle of Tomb Raider 2...duh!
I still have to finish T2...never finished it, thats what Unreal did to me.
In the end that system slowly died as I think the faster CPU speed was tearing up PC parts slowly, I managed backing up my HD in time before it died.
