I barely realized this but it has been bugging me for the last two PMX. The lights! Everything seems too dark to me, more light would be appreciated specially in the dealer's room and artist alley.
I will put a bet that the extra lights will be at the dealer's disgression since the lighting is not the fault of PMX staff. However, I do hope that there will be more light as well since, dim lighting can cause eye-strain and tripping hazards.
