I've always wanted a chivalry e-sport. I was certain mirage would take off internationally and it would actually perfect for the e-sport fps scene: skill based melee, a healers, class roles, team composition mattering, draggable ranged abilities, the skill ceiling in mirage I think is higher than chivalry's given it is essentialy chiv's combat with addee things like first hit flinches and skill associated with working effectively in a team matters much more in mirage.

With that said mirage is less popular than chivalry atm so unless that changes it has no chance at becoming a true esport.

Warband had a professional type of tournament similar to mlg recently in Europe somewhere iirc, so maybe one day mordhau, mirage, or bannerlord could become an esport. That would be pretty cool.

Another thing though that worries me is say mordhau becomes an esport - will there be the neccessary support by devs to balance, and most importantly how will they ensure that it doesn't die like starcraft 2 did? I think that is the most important esport to study as sc2 had a glory days during wings of liberty and a bit in the first expansion but by the second expansion the proffesional playerbase was all evacuating sc2 to get into other games - mostly MOBAs. Why are mobas doing so well? Is it teamwork aspect? I dunno I never liked dota back when it was only dota 1 and I like other customs in warcraft 3 a lot more and even base warcraft 3 skirmishes I like more than dota.

So I guess what I am saying is it seems team aspects while preserving individual skill seem to do well in esports so while something like sc2 can become an esport it cant stay around as an esport since it is too individual based. So these are things devs should consider if they care for these things. In reality I think it is more practical to create a fun game with interesting mechanics that people will like and hopefully it takes off.
