While I was surfing the Abandonia forums I found out that some people are working on a client that will let Ultima 8 run on current OSes.
I actually said, "WHY!??!!" aloud when I first looked at the above page since Ultima 8 was horrible. Now, I'm a person who really likes abandonware and I play old games intently to really suck the marrow out of the history of gaming; I once went over to a friend's house and we battled to beat Night Trap on the original Sega CD system for hours one time and that should give you an idea of my dedication.
I remember, though, playing Ultima 8 on my old 486 machine as a kid when Ultima 8 was value bundled with some Soundblaster software and equipment. I didn't own any of the earlier Ultima games and I was eager to see what was all the fuss was about so I installed it and played it.
It was horribly broken. Besides for the fact that Ultima 8 had a documented plot bug I would have found it impossible to progress in the game if I hadn't been operating out of a walkthrough. There were loads of invincible NPCs and lots of situations which would trigger instant unavoidable death, such as if you so much as picked up an item off of a shopkeeper's table. (A magician would actually teleport in and detonate you, no shit. You were forced to stand there and let him do it, also; your controls locked up so you couldn't fight back. To make matters worse there were certain spells that made you immortal in various ways and as I recall it was possible to crash the game big time by managing to survive events that were supposed to automatically kill you.) The clues leading you through the game were so ridiculously tenuous that I enjoyed the game playing as I read from a walkthrough but if I didn't have a walkthrough I probably would have quit playing in frustration after a few days. What an epic combination of a giant armored plot wagon with spiked wheels which drives over your skull and pops it and total lack of directions and clues about how to get on that plot wagon.
Wow, just thinking about it makes me smirk and snicker. The goal of the game is to kill all of the gods of the world so that you can return to Britiannia, but god forbid that you pick a mace off the blacksmith's table. That spells immediate doom for the god-slayer.
Anyway, the FAQ for that site says that the engine is similar to the one used for Crusader and that they hope to eventually have a nice Crusader client. I suppose that that's a reasonable reason to work on that project. I haven't been able to play Crusader but it's got a good reputation. But, good god, without Crusader, I think that the idea of someone making a client so that you could play Pagan again on your current machine would have made me lose SAN points.
EDIT: I would rather play Night Trap than Pagan. Seriously. At least Night Trap has some marginal entertainment value. Pagan doesn't really have entertainment value. Instead, it has something I might describe as "it makes me want to stab myself in the groin with a rusty steak knife" value.
