I've read the meagre manual, played those uncaring short and not very explanatory tutorials and still those settlers don't really function and I don't know why. If they can't, by tutorial or manual, show how the game is played, then it's not good. I've built houses like mad and still had hardly any soldiers. When I wanted to attack, I've got like 3 soldiers coming to war. All houses seemed to lack stuff, but there's no obvious way to manage what does from where to where.
I played Diablo 1 for many years, I have the CD. I bought this pack here on GOG to get rid of the hassle with the CD (copying to harddisk and installing a virtual CD software that I don't need otherwise), and because I was curious about Hellfire, which I did not have. The strongest reason was that my Diablo kept crashing when I tried to switch from the game to Windows 10 desktop (ALT TAB). Since I didn't see anyone complaining about that, I had hopes that it would work. And it does. No more crashes. Great work! Besides that, Hellfire is really a must have for Diablo 1. For the little money the package costs on GOG, get it, even if you own the CD, but missed out on Hellfire so far.
Worst game I bought so far on GOG. It never worked from start to end, when going to more complex games. 3 players, longer games, that game just got overtaxed. Sometimes it got stuck, when switching from one player to the next, sometimes units wanted to move but couldn't anymore, slowing down the game, sometimes, when starting a new round, you selected a construction unit, that was blinking (for having done the job), and then when it started to move, the game crashed (overflow). The "sometimes" applies to playing before round 150 or so. After that it switched to "usually".
