Bash at the Beach: Bash at the Beach was a yearly professional wrestling pay-per-view (PPV) event produced by World Championship Wrestling (WCW).  It was the company's PPV for the month of July, held from 1994 to 2000.  The show centered on a beach theme, with the set around the entrance area for the wrestlers decorated with such things as surfboards and sand.  The theme for the show seemed appropriate for an event scheduled during the hot summer month of July.  The beach/"fun in the sun" theme was also reflected in the places where WCW chose to hold the event; all of the shows emanated from cities in either Florida or California, two United States states renowned for their warm weather.  It was WCW's response to WWF's SummerSlam.  In 1992 and 1993, WCW held a beach-themed pay-per-view show known as Beach Blast, which was the forerunner to Bash at the Beach.  The 1992 show was held in June, however, as the company elected instead to reserve July for its flagship summertime extravaganza, The Great American Bash.  Along with Slamboree, Starrcade, SuperBrawl, The Great American Bash, and Halloween Havoc, Bash at the Beach was booked to be one of WCW's flagship events.  WWE have owned the rights to Bash at the Beach since they purchased WCW in March 2001.  In 2014, all WCW Bash at the Beach pay-per-views were made available on the WWE Network.

WCW/nWo Thunder: WCW/nWo Thunder is a video game based on the professional wrestling TV show "WCW Thunder" and released on the PlayStation console by THQ in 1998.  "Thunder" is the sequel to "WCW Nitro" and updates the previous game with new characters and features, including cage matches, battle royals, weapon use, and the ability to select what stable each wrestler competed for (this included WCW, nWo Hollywood, nWo Wolfpac, Raven's Flock, and The Four Horsemen).  However, "Thunder" received poor reviews.  Many of these were due to its graphics, style, and overall atmosphere, which bore too many similarities to "WCW Nitro" (e.g. all the cheat codes were exactly the same).  A modification was also made to the control scheme, which allowed players to wear down and easily beat the opponent simply by winning grapples repeatedly, hitting your opponent once and then pinning them in around 30 seconds.  This contributed to the harsh reviews the game received.
