Arc System Works is rereleasing its 3DS open-world RPG brawler River City: Rival Showdown on Nintendo Switch on 12th October 2023 in Japan. A western release hasn't been confirmed yet.
Confirmed via this week's issue of Weekly Famitsu (via Ryokutya2089 and Gematsu), the game was originally released as part of the Kunio-Kun series' 30th-anniversary celebrations. Developed as a remake and reimagining of the third game in the series, River City Ransom, and adds multiple different story paths, endings, and an open-world setting.
The 3DS version was released in the west in 2017, and we really enjoyed our time with it back in the day, rewarding it an 8/10, stating:
"...between the meaty campaign and the fun side mode, River City: Rival Showdown will likely hold your attention for some time."
