Now What? (Skirmish Edition)

So Far

What have I completed?

1. I decided to make counters to use for arena battles.
2. I designed and printed counters for 13 different factions.
3. I stuck the labels onto bases, giving me completed counters for 2 factions - dwarves and goblins.
4. These two factions met in my first arena battle.

Now What? A Skirmish Campaign?

t would make sense to complete the counters for the other 11 factions. But I find myself getting distracted by other possibilities, specifically the idea of a dwarf-goblin war campaign. I would follow the exploits of a band of dwarves as they fight to clear a goblin infestation from their mine.

Considerations

First, what rules should I use for the campaign itself?

• I'd like something that will generate diverse missions and will allow my dwarf warband to improve over time.
• I don't want something that requires me to track a lot of resources. That was the issue I had with Five Clicks, a post-apocalyptic game by Nordic Weasel.
• I will probably write my own campaign rules. In the meantime, I'm perusing various wargames for scenario and campaign ideas.

What additional resources do I need?

• I feel like I need more grunts for both sides. Also, I envision running into some monsters, like trolls. Now I need monster counters.
• Terrain? I could just use the terrain from my MicroBattles Big Battles set. But I'd like to put something together that is more skirmish-y
