I think Warcry is the best skimirsh sized game and with the last Tome of Champions it does provide a better campaign experience than Mordheim.
I'm currently in a mordheim campaign, and this game is frustrating, the snowball effect is real. Mordheim is an amazing setting with bad rules. Just play Warcry if your like the AoS setting. Sor-Koroth the silent city is a cool place to have warbands hanging out and fight others for loots and territory.
But Frostgrave does magic better, i you want to play wizard in the AoS setting and with skirmish scale, yeah Frostgrave is pretty good. I think it needs a bit of adaptation to integrate the Endless Spells. We have tons of good miniatures for the spells, if someone can come up with an AoS version of Frostgrave it would be pretty cool.
Rangers of Shadowdeep is a good solo experience, and with this damn pandemic, it does provide a satisfying boardgame / rpg feel. I would really enjoy a Rangers of Shadowdeep campaign in the Sigmar setting.
Never tried Oathmark, kingdom building sounds pretty cool tho.
