none of what you have said is different from past new ore suggestions if you want to resurrect a denied suggestion you need these things and even then its a long shot depending on peoples moods
1. it must be well thought out, you must have all the hard numbers and balance stuff worked out in a way that is detailed and makes sense.
2. it must be well presented, the best presentation is a proof of concept addon, but videos, pictures, and concept models have been well received in the past.
3. it must have a unique spin, you must have truly worked your noodle and came up with something cool we never thought of.
these are not set in stone nor are they offical rules but they are your best bet for not getting flamed out by every one saying
"DENIED ALREADY!!11!!!1 N00BS SHOULDN'T BE ABLE TO START NEW THREADS!11!!! "
also on the flip side don't make it to long cause then every one will say "tl;dr DENIED ALREADY!!11!!!1 N00BS SHOULDN'T BE ABLE TO START NEW THREADS!11!!! "
