dunno if there is one or not but i couldnt find one so hear is my request (not really a request, its too much to be a request, so more of... an offering of assistance?) :
it will add:
skills - each with its own xp and levels and unlocks eg
Tree cutting
cut logs from trees that will grow back after like 1 hour of game play? but get like 2, 5 or 10 logs per tree or something and use them for other skills or just sell them
fletching
make bows/x-bows or arrows/bolts to use by cutting logs
alchemy
making potions, picking herbs, harvesting things like roots, seeds ect and making poisons for weapons
craft
making jewelery/tools/whatever else
traps
build traps form wood/stone or w/e and place them but... i dont know if it will work well or not. u could add another fight thing in eg: enemies wonder aimlessly around the map and if u get too close they run at u and fight u or fall in a trap or something
fishing
use a fishing rod to catch fish
cooking
cook fish, bread, meat ect
smithing
make weapons and armor and arrow heads ect
mining
a way to get ores for smithing
come to think of it these could be done w/o scripts... i might try it with common events, just use conditional branches for requirements, variables for exp/level ect and yay, i can do it myself! but if anyone wants to have a go at this using scripts go ahead =D
but the trees growing back would be hard to do... unless there are timers of some sort, im fairly new to RPG Maker XP... i only found out about conditional branches about 2-3 moths after use =P
but anyway, ur free to try this if u want!
just gotta draw icons and stuff (graphics is my weak point)
