I'm coming in this neutral since it does seem to be getting hostile.
I love SEGA's games (even the ones that get critiqued), and I love Nintendo games (even when they have their own problems).
Personally, I hate to see any company critiqued whether they have a lack of IPs, have too many IPs or whether their portfolio is good or not.
Of course, there is always a good discussion about SEGA here and of course some may mock other companies from time to time, but I do hope that it's never serious because at the end of the day we're all gamers and acknowledge each companies weaknesses (including SEGAs).
When I wasn't active before, it was more a lack of news on SEGA's side, but the news of games has me a little bit more excited than usual, and I wish SEGA the best to continue the good will.
At the same time though, they do seem to be backing off on console development, but as a company, they do what they have to do.
You know what company I've noticed making more and more IPs every year? Tecmo-Koei. Granted I used to just know them as the "Dynasty Warriors" company, but I am really respecting them for their new approach with their list of existing IPs as well as their new ones (DoA, Ninja Gaiden, the Atelier Series, Ar no Surge etc). I am pretty surprised actually, and I do hope that one day SEGA and TK collaborate on something incredible as the two seem to provide something the other couldn't in my eyes.
Anyway, that's my take on the thread, and I hope it doesn't sound like I am defending SEGA or Nintendo in this case, as I do love what they both do in their own way and see a little bit of one another in their gameplay sometimes.
Edit: The point about no one likes Valkyria Chronicles. I do, and I wouldn't like anyone thinking that one franchise replacing another is a bad thing. In this case, Phantasy Star and Valkyria Chronicles are too different to be related, so it's not been replaced at all.
