Its relatively OK. If you look at the bigger picture, that in order to play DCS you need a high-end gaming PC, decent HOTAS, a headtracking device, plus a few modules its OK for a hobby that can offer thousands of hours of unlimited gameplay PLUS it continually adds more content and improvements.
My brother in law has one of the most expensive hobbies - hunting. A decent hunting rifle can cost up to 12,000+ euros, plus licences, maintenance equipment, ammo, hunting dog, etc, etc... Now that is an expensive hobby!
