Source-derived summary

Sega AM Research & Development No. 1 is a development department within Japanese video game company Sega Corporation that also previously existed as Wow Entertainment and Sega Wow Inc. AM1 spent most of its early existence under the leadership of Rikiya Nakagawa and developed a number of arcade games for Sega.

In 2000, Sega split its development studios into nine semi-autonomous companies, with AM1 becoming Wow Entertainment. Wow developed games for the Dreamcast and later other consoles as well as arcade games. In 2003, as part of studio consolidations within Sega, Wow was merged with Overworks Ltd. (originally titled Sega CS Research & Development No. 2 and later AM7) and renamed to Sega Wow. Nakagawa resigned a few weeks later after Sammy Corporation acquired a significant amount of shares in Sega. Sega Wow was re-integrated back into the company the next year.

Editorial analysis

Why this record matters

“Sega AM1” is worth following because a concise public description often conceals a longer documentary argument. Here, Sega, video and game provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 16, 2026. The linked authority identifier is Q339565. The first chronological checks are 2000 and 2003.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
