145 usd/122 euros, for the limited founder pack for sea legends is very steep, its more price than ultimate edition games of triple a developers for instance.

Also, i've been playing naval action since it came out in early access on steam in 2016 and i clocked more than 2000 hours into it, also i own all the dlc.
