Considering this, we will have to thank the modders twice:
First for not only spending spare time on working on this game and being kind enough to release their work for free (the pay will be an unmatched amount of fame and glory at least).
And second for actually buying the game in the first place to be able to work
on it and making it worthwhile to buy the game for many other people at last !
(Not that anybody is buying the game out of pure charity with the community - but still...)
So far, I for myself have done and released only some interface work for SH3 and some textures for SH4 and that already taught me how quickly a hobby can turn into hours of work, depending on how perfectionistic you are.
