Yeeeaaahhh 
[sarcasm] Let's all make TF2 stuff while raging at all those Halo fans! [/sarcasm]
Or we could be original, and think up our own neat crap. Ooohhh, but that might be too hard, lets steal other peoples ideas.
You know what, you're right! In fact, let's delete skyboxes, those are SO used in every other game! What about pistols? Too original! No AK47's, no Team Deathmatches, no TF2, no nothing, not even bricks, ROBLOX has those, hell, Eric, you're losing the game's originality!
