This is probably heresy, but isn't Nightlong a port from the PC or Mac version? If you really want to play it now and the Amiga version is dog-slow (no doubt not unlike Clickboom's Amiga Quake), you could probably buy a complete second-hand pc setup suitable to play it for much less than an A1200 68040 accelerator card alone. Heck, brand new complete Athlon XP systems are going right now for around $350. A novel idea would be to put your A1200 in a big tower with the pc and then network them together like Eyetech used to do or simply toggle between displays with a monitor switchbox. Then you could have your A1200 tower and still play the occasional older game on pc. Or, if you don't already own an A1200 accelerator card, buy Amiga Forever and have your 68020 A1200 virtually in emulation on the PC. The choice is yours, but unless you're a hardware purist, rather than plop down $400+ on a five-year-old-overheated-second-hand BlizzardPPC off eBay, I'd be saving my real pennies for a brandy-new Micro-A1 and OS4. There will likely be some kind of useable 68K and PowerUP/WarpUp emulation in OS4 to play the older 68K and PPC amiga games on the newer G3 and G4 chips.
