I tend to agree. I think one of the things I enjoy most about Sega is how truly diverse the company is, because of a rather long history of no third party support. Sega has a very deep stable in damn near every genre to put into the fray, but they never really seem to do much with them.
For fighting games, Sega has how many franchises? Virtua Fighter, Fighting Vipers, Last Bronx, Eternal Champions, and on and on. They have lots of racers; Daytona, Sega Rally, Sega GT, Ferrari F351, OutRun, Sega All-Stars Racing, Virtua Racing. They have RPGs, they have rail shooters (HoTD, Let's Go Jungle, Ghost Squad, Virtua Cop, Panzer Dragoon, Rez) platformers, pet simulation (Seaman), dance (Samba, Space Channel 5), first and third person shooters, sand box games, brawlers (Streets of Rage, Die Hard Arcade), games that defie genre. We have ninjas, shape shifters, date simulator/mech battles, SRPGs, straight up mech battles, bug battles, space operas and Space Michaels, air plains, falling blocks, tennis, survival horror, survival horror in a submarine and so on and so on and so on.
I like it when Sega is running on all cylinders, and I frankly wish they were better at keeping some of their games going, a bit better. That is one thing I wish Sega could learn from Nintendo; keeping your franchises relevant. It feels like Sega is so sporadic. From 1998 to 2002, we had three House of the Dead games, a House of the Dead brawler, a House of the Dead pinball game, and a House of the Dead typing game. Then it just dries up for years, until we suddenly get House of the Dead 4, Typing of the Dead 2, House of the Dead Overkill, House of the Dead EX, House of the Dead 2&3 Return, and whatever else. It's always in bursts with Sega. We had about 9 Shinobi games between 87 and 95. Then we got one in 2002, one in 2004 and then one in 2011. Sega's been trying to reboot Streets of Rage since 1996. I have no doubt Shenmue 3 will come - just, when it does, I'll probably be retired.
