wow rly? how could it RUIN it? i mean,you cant do all that much without, you can make comics and weld stuff together to make a (probably unrealistic) barely working contraption (that really depends on WHAT it is), and most of it really isn hard. wire a thruster to an adv. pod and you can actually CONTROL it, instead of using the numpad. wiremod made gmod better, it didn't ruin it at all. it CAN be kind of complicated, but take 5 seconds to learn it and it makes things WWAAYY better.
