Well, I know that most, if not all of us realise that we're not going to see any sort of modding tools until after the game finally goes gold for the simple reason that the game changes every patch and update, especially the mesh files and how the game uses them. Anything we've changed would have to be completly redone to work with the new game, also why our saves between versions are useless. However, it is nice for us who love to tinker with the game to be able to tweak the values just to find that happy point where everything works great. Like for example, I really enjoy the change to the Gauss Cannons. I've tried messing around with the values, just like everyone else here. And I agree with lordkosc: 3 shots at 8.5k range really made the game something better, even if I was on the receiving end.
I just think it was very trusting of them at IronClad to keep the code so open like this that we could almost completly remake the game if we wanted. Want that LRM Frig to be able to take down a Kol in one Salvo? Go for it. Why? Because I can and because I think it would look cool. Is it going to make the final game? Oh hell no, and you should be smacked with a frozen trout for even asking.
