randy pitchford says people who mod are helping the game, and on a side note there is going to be a third playthrough
Some of the combinations become game-breaking, and it puts stress on systems. Sometimes we get reports from customers of fatal flaws and crashes and things, and they dont make any sense to us. Then we learn theyve modified their game; theyve actually broken themselves and theyre outside the bounds of what the programmers anticipated.
Its funny to think that fans who have the tech knowhow to cheat the system are, on some small level, also helping to poke holes in it that might have been missed before it was too late. Its not encouraged or appreciated by Gearbox, but the unintended benefits are hard to ignore. When people cheat, you get actual test cases that demonstrate how the game breaks when certain limits are exceeded.
