I agree in some ways but I do feel there is potentiality in bringing back key franchises. I think one of the easiest ones would be something like Jet Set Radio, considering that the concept behind that game is still popular among fans and being a pack-in title with Xbox made it reach a new fanbase that they never capitalized on. I think Jet Set Radio as a franchise can totally have room to grow, for example having better custom tags in different graffati style, online play that has 'king of the hill' type multiplayer. LIke there are 3 map matches, the best of 3 wins (aka people running around taking bigger spray points, each one with their own point system). I think graffati art has grown way bigger than it was when JSR and JSRF came out thanks to people like Bansky and the such.
Its easy to see for that franchise.
I can even see Crazy Taxi being a popular game if handled correctly. Single player focusing on what made the original fun, with loads of customizable Taxis, tons of stuff to unlock and the like. An online play where you and other taxis drive aroudn trying to get the most money until the clock runs out will work so well for this franchise.
There is nothing wrong with doing Alien games, In my opinion that has nothing to do with the quality products released in Japan. SEGA Japan needs to improve their situation and actually make games of quality, the West is already making quality games for a western fanbase and there is nothign wrong with that (in the end of the day, that is their job, to cater to a western audience)
SEGA Japan just needs to be able to make a product that is of equal quality to the Western brand of games (Like Isolation) but with the style of a Japanese developer, I hope Satomi is right in what he said. While personally I rather see their first 'quality game' be a new franchise then slowly bring legacy IPs when they start having success not only in the quality of the game, but selling the fucking game in the west.
