SOSU

So after Joy of mapping 5 i am going to start another project,but what exactly should i do?Should i:
1.Make a sequel to Scrap Metal? (This would take me 1-2 weeks to make)
2.Turn Serious Sidhe into a Full episode? (This would take me 1-2 months)

3.Make a 2 map Heretic project using some Strife enemies and textures? (This would take me a month
4.Make a multiplayer map (This would take me around a week)
5.Plan out a little community project consisting of me and around 8 other people making a Heretic episode with an extended monster library and using medieval textures from Realm 667 (this would take me nearly 6 months)
