Your offer is very caritative
Around 1 year ago many modders (megyaem30, rogerfed1, me, inter alia) would thank this, because we made many content with an unofficial version of the game.
Fortunatly, all we got the full game one way or another at that time
Currently the modding of Tennis Elbow isn't in its best moment, the quantity and the quality of the mods is reducing and the best modders are reducing their yield
If you really like the game, i would suggest you to buy the game for a friend or relative (or reserve Tennis Elbow 4 when available).
