I am giving my game lots or replay value to it, this is only 1 of many features im putting lots of effort into, not only do i use a tax script but i modified it to also have a haggle system, thanks to your help
And taxs will vary all the time depending on world events, during more dire times they will be higher and during peace they will be lower, they will also be based on a random generator, each shopkeeper will be different too and taxes can be droped way down or completly cut if you do a quest for them.
Basiclly im going for the most realism possible, I want my game to be well known as the most realistic and feature driven 2d game. I was a big fan of oblivion for this, it was very open and gave you lots to do, you could spend years playing that game and still see everything. The main quest in oblivion was probably only 1% of the game, it had so many side features and guilds and areas to explore.
