Yeah but with games like Iron-Man, Golden Axe: Beast Riders and Sonic '06 being the first Sega games after the merger, it shows a dip in quality of games afterwards for that era.
Iron Man was a success though. The follow ups (Incredible Hulk, Thor, and Captain America) sadly weren't.
There were also Phantasy Star Universe, Yakuza 1-2, After Burner Climax, Dinosaur King, and Outrun 2 which were also successes.
