Diablo and Neverwinter Nights cannot be compared! Diablo is the best for action hack'n'slash fast-paced multiplayer pc rpgs, but Neverwinter Nights delivered to the mod and pen/paper role playing community. For the first time you could simulate Dungeons and Dragons on the PC-the DM client was the first of its kind, and the aurora toolset was beautiful for the fact that it was included with the software. But, Neverwinter Nights has serious hardware requirements.
My friends and I like the same types of games. We like action games, and humor games, and when I forced a friend of mine to play Zelda128, he got a gameboy sp and the remake of Zelda3. Game development in a group is easier if you are not trying to make "the best <insert genre here>". That starts flame wars.If you have a group, decide on a genre/concept that everybody likes, and don't try to change the world...yet. Start by making a game that is just plain FUN and SOLID. Our eyes were too big for our stomachs for our first project, and we've since toned it down to having a goal of being just a solid and fun FPS. We may plan to do some crazy sequels, but we're starting with a general idea that we ALL know will be enjoyable.
