You can defintely run that risk when getting into mods...but for me thats the trade off for being able to exercise my creative side. I build and create a lot of things, and it makes
me feel like ive accomplished something. Its very satisfying. Especially when the finished product turns out how i wanted it to. I love working with other people as well, creating a thing of beauty together. And the friendships ive made while modding are worth it to me. Thats the way i see the money spent/lost. We cant take it with us when we go. But i can totally see your point.
