So, I wanted to clearly separate my Historicals from Fantasy gaming. I have quite a few minis that can bridge the gap, but this is its own creature. Although I have not yet had a chance to play any out in depth, there are three systems I plan on using primarily.
1) THW has Fantasy rules for Rally Around the King Ruleset as well as the historical ones. These will be great for solo gaming.
2) I have everything from the old Clan War system from AEG which has always been interesting and I have quite a few of the fantasy minis, from dragons to ogres, to orcs, etc.
3) I got a copy of the D&D Battle-system and Skirmish on Ebay and plan on using them to integrate into any RPG campaigns.
