This is where you start. The ''myth'' is that you randomly walk over to your ''best'' friends and say ''I got this super cool game, lets play!", and then somehow you all ''magically'' have a great fun time.
So right from the start: Don't do that. To just randomly group some friends together guarantees different ideas and goals. What you want to do is find people that share the ideas and goals that you have, and befriend them and make a group.
Well, you should always have fun.
