I don't get the point of this discussion concerning guest characters. If you don't want them, don't buy them, it's simple as that. Your MK copy will stay "pure"... I didn't like Freddy being in MK9 and I didn't buy him. I've only purchased Rain back then. In MKX I enjoyed playing as Jason, Predator and Alien because they were better fighters than many SF MK characters. At least we had more non-human fighters thanks to the guests.
We discuss a game on a forum. It is definitely not okay to offend people because of their opinion. Some people here do not tolerate anything that is different from their point of view. Why bother to discuss anything with other people then?
I am not a big fan of guest characters but it doesn't bother me if there are a few of them as DLC. We already had Kratos, Freddy, Jason, Leatherface, Alien and Predator. Many friends of mine that have never played MK before liked the guest characters and got interested in MK as a whole which isn't a bad thing. The guests come from other gory franchises which is fitting the lore. It's not like NRS is adding Shaggy, Bugs Bunny etc.
I've read things about "liking guest characters" = "not being a real MK fan" which is bs. If you are a MK fan, you'll be happy about MK games being successful. 10 years ago I was afraid I'll never see a MK game again. After Armageddon and MKvsDC everything was coming to an end and if guest characters make MK more popular and successful, I'm fine with it. Because even if I don't like the guest characters they release, I am still able not to buy them.
I'm ok with guest characters since they are optional, so as you said, it's absolutely a personal choice.
The whole point, at the least for me, is that the more guests, less MK characters. Would I like guest characters? Nope. Do they make the game more popular? Yes, and it's good thing for sure, it was really disturbing the gap until MK9. But a game like MKX had a Fujin sitting out of the game despite being almost necessary and a Leatherface in. There were four horror characters that had nothing to do with the game itself. It wasn't like Freddie or Kratos that were merely bonuses. So I wonder: what's next? 10 guest characters when we have plenty of characters that could get way better than the poor development they had? So we are going full Terrordrome?
NRS has a limit, but I highly doubt that if a character could be killed in cold blood and it was a popular demand they wouldn't add. Shaggy is a joke, despite being a comedy cartoon character, and he's a good one, but not for MK. Still, I don't doubt if any BS character had enough popularity they would put, and here comes "because sales".
It's nice to see other people that don't know MK buying the game, but I'm sure they will prefer tons of guests instead of MK characters.
But who's offending? This thing about "liking guest characters" = "not being a real MK fan" isn't actually for real, at the least for me. Many people in this forum are die hard MK fans and love guests, I can respect that, I just wish that MK doesn't get twisted into a mess where you can throw anything, that's the point of the argument, nobody here is gonna change WB's mind, still, it's a forum, so the point of discussion is basically discussion itself, clash of opinions etc.
I don't think anybody is taking personally. I hope.
