I’ll go into what I see as the strategic situation vis-a-vis the two of us, Mysterio, but if you turn around and win because of my post, I’ll laugh at myself very sardonically.
First: You don’t quite seem to realize it, but your position prevents anyone from successfully seeking enough successful vendettas against you for a long time. Yes, I’ll be able to claim vendetta, kill your legion, and gain some Prestige off that, but after that, I can’t take your Stronghold, and I can’t even succeed in a Vendetta unless you set it up such that I can, so there is zero chance I can call Blood Feud.
For the record, the options in vendettas are: Single Combat of Champions (eg Praetors), Capture X Cantons, Destroy X Legions, Capture X Places of Power. Succeeding in a Single Combat vendetta does not count as one of the three you must do before you may claim Blood Feud.
Second: Four tribute cards is an annoyance early game, but it’s far from a serious grievance, especially when my Legion would have had better things to do than hover around your base so I could keep demanding tribute from you. I thought I demanded only three, too.
Third: You can quite competently turtle for quite some time in SI, build up your attributes, harass other players with Rituals and by constructing Machines, and pull out a win.
Fourth: Combat cards could potentially allow you to take down a very strong legion with a much weaker one.
Fifth: Well, you could go Blood Vassal… I kid, I kid! Unless you have Kingmaker or Power Behind the Throne. Ahaha, wouldn’t that be a hilarious turnaround. No, seriously though, you’re far from out of the game at this point.
