The GOG version is great and runs great on modern hardware. Blood was my favorite FPS as a kid.

Really? I'll have to check that out when I find the time.

If it is like many of their old games, it's just packaging a dos emulator with the game, giving you a single click experience.

Oh. Well then, I may as well buy the disks and edit the dosbox confs myself.

Well...yes, but in your other comment, you said that it would be difficult to run on your computer. You seemed happy when Dakull mentioned that the GOG version would be trouble-free, and then you seemed disappointed when you heard how it would be done. That confuses me a little.

With the current Dosbox defaults, the game installs nicely, is easy to configure, and runs well. Based on getting the demo running just now:

Extract the files somewhere. Mount the directory in Dosbox. Mount another directory as an install location. Run the install (the demo's is just install.exe). The installer drops you into the game directory when it exits. Run setup.exe. Select Sound Blaster for the SFX, and either Sound Blaster or General MIDI for music (personal choice). Save the configuration and exit. Run the game (blood.exe). Oh, I also set it to 800x600 resolution, when given the option to set a display mode (it's available under the VESA setting).

I see Blood available on Steam for $4.99, on GOG for $5.99...or on Ebay for various higher prices, if you really want the hard copy and the classic-ish setup experience.

Maybe it's just me; but games played in dosbox never feel... right? That's my biggest gripe with it, at least.

gog is pretty awesome and it'll be a drm-free game download anyway. I've always felt pretty good about paying them for games.

Did I mention it comes with all the goodies [0] and "DLCs"? but even without that memorabilia (original manuals) the simple fact the the game just runs great is worth the admission price.

I wasn't there at the time, and it's really hard to actually run Build games nowadays. You have to run DOS, an emulator, or one of several not-entirely-functional sourceports. None of those options are really appealing.

It might not be really appealign, but once you take the plunge, is there an actual problem?

Getting it running on my computer is hard: that's a pretty big problem.
