How about the following?
Wargames Atlantic Team up with Producers of Historical Tabletop Rulesets and bring something similary to Warlord Games "Epic Battles" Range?
Warlord Games Epic Battles ACW and Napoleon Ranges are very successful and WGA could "steal" some profit from this.
A own Range of 15mm Miniatures combined with an existing Ruleset. This could work for popular Settings Warlord Games do not cover.
Otherwise; when WLG brings a Hail Caesar Epic Battles Range, WGA could produce similary Miniatures but for Stuff WLG does not cover.
What does the community thing about that Idea?
