I should also consider the target audience. Are they Japanese gamers, or is it more of an international audience interested in video game history? Probably a mix, so explaining Yakyuken's place in Japanese gaming is important. Maybe mention how it contributed to the genre locally. Also, the transition from disc 1 to 2 might have been a way to keep players engaging with the IP, common in Japan where baseball is popular. That's a point to elaborate on.
