Hello list, I'm doing my very first game, which mixes Space Invader type shooting and role-playing gameplay. I have a specific newbie question regarding character advancement design: How are experience point numbers for character levels set? For example, let's say level one needs 100 exp points, level two needs 200 points, and so on. How come these particular figures? Are there any formulas out there for setting up this numbers? Many thanks in advance for your help. Douglas
