Believe me. There are people that complain about other fighters doing it as well. People tend to especially be more vocal about it when it's a Capcom fighter.Are all you people who are bitching complaining about every other fighter that does the same shit, too? Tekken, Soul Calibur, Street Fighter, DOA etc.
Aside from it just flat out being worth it to me, think about it this way - Super Mario 3 for NES cost as much or MORE than you just paid for MK11. I remember seeing it for $75 in a store once as a kid. Games haven't gone up in price since then, and they cost a boatload more to make for obvious reasons. New releases cost the same then as they do now.
I'm not saying WB/NRS is hurting for money, but to get as much content as we will end up with in MK11 for $100 isn't some sort of insane ass raping. For the amount of work put into this game, it's well worth it to me. And again....you don't HAVE to buy the DLC. It's simply an option.
Thing is, things really weren't much different back before DLC. There was a time where the developers would add more content and charge you 50 to 60 dollars by calling it a new title. So if DLC didn't exist, we'd just be back to what happened in the past. For example, MK11 would just release with the base roster characters and then about a year later get an updated version with the DLC characters and maybe some game tweaks. Either that or the DLC characters wouldn't be in the game at all.
