Yes. A long title for a post that will cover some things that can make it easier for a game to be played.
HP system - when it goes to 0 you go to a page that says you died. Limit one so the game won't crash if someone made two and both died at the same time.
Variable Caps. - Lowest possible to Highest possible. Goes with HP system.
Multiplacation Effects - Instead of the basic adding and subtracting you can multiply and divide.
Percentage Effects - Like multiplacion effects except you can put in -10% or +23%. No multiplacation or division is aloud for this. If you have this you probably won't need the multiplacation or division effects. This sets it up as itself.
Battle System - Check out Kaddar's Thread - Nice Site, Suggestions.
Alex, tell me what you think of these. The percentage one is an origanal. You can find the other 4 in basic RPG and battle games.
