When they're good, they're awesome. Valkyria Chronicles was my favorite 7th gen game, and I bought the deluxe edition of VC4 for the Switch on launch day. Yakuza is also good. I'd like to see Sega explore more Japanese SRPGs, especially after how well Nintendo did with Fire Emblem: Three Houses.
But their marketing is completely clueless - not only do they not market well, they have a bad habit of sending games out to die against major blockbusters and have done so for over a decade. And they have too many dormant franchises. Where is Virtua Fighter 6?
