I'm a +/- 0 for this idea. Reasons:
1. Yes, it will bring more people to meep, but only if it works. Considering meep's current track record with keeping minigames up, this is more likely not to happen then to happen.
2. We already have games in this category. Want to make holes that people will fall in? Go to TntRun. Want to kill people in a minigame? TntRun, Boomo, or Halo.
3. This is not totally necessary, for reasons mention above and in other posts, but will be another thing that the staff will have to moderate. This translates to more work for the staff.
4. If this minigame give meeble rewards, which I presume it will, it will only add more money to the economy. More money in the economy means more inflation which means that the meeble will lose value.
Bottom line: If Splegg comes to meep, please staff, make it not overly complicated, so that it will be up more of the time, and don't make the meeble rewards too big. Doing these two things will prevent the damaging of the reputation and first empresion of Meepcraft and the value of the meeble.
