the type of shot chosen. Generic tennis moves, such as slices, dropshots, and lobs, can be applied at any time in the match. Development Power Tennis was developed by Camelot Software Planning, with a team of approximately 30 people, headed by brothers Hiroyuki and Shugo Takahashi. The game was first unveiled in a 2002 issue of the Japanese magazine Famitsu, and was later presented at the E3 conference of 2004. Before release, the brothers discussed multiple developmental processes in an interview with Famitsu. Camelot had been working on a previous GameCube version of Mario Tennis, but discontinued the project and began again using ideas and technology from Mario Golf: Toadstool Tour, which was being developed simultaneously with the game. Shugo noted that the original would have been more serious and contained deeper gameplay, but with fewer "Mario-esque" gimmicks. There was also a willingness not to update the graphics only without exploring advancements to concepts and gameplay, which Hiroyuki stated would be "unacceptable for a Mario game". Due to the success of its predecessor, the brothers felt pressure to make a game that was original and would not appear too similar to its predecessor on first sight. Following release, IGN interviewed Hiroyuki regarding the development of the game. He revealed that Camelot had received co-operation from Nintendo in relation to voice acting and animation, which Takahashi stated as "contributing quite a bit to the improvement of the game's graphics". Takahashi proceeded to explain why the role-playing game elements that were present in Mario Tennis were excluded from Power Tennis, stating that he felt they were more suitable for the "deep single-player experience" present in portable consoles. Regarding the themed courts in the game, he explained that the concepts were conceived during long brainstorming sessions, with courts selected that would both remind gamers of older Mario games and introduce new gamers to Mario games they may not have played. When questioned regarding difficulties in developing the game, Takahashi noted the effort used in making the opening sequences, developing the Special Games, and animations, which caused problems with meeting the schedule. Although there was speculation about online capabilities before release, Takahashi refrained from making the game online-compatible due to fear of lagging problems, stating "I don't think you can play a tennis game online under the current Internet environment and feel satisfied". Nintendo collaborated with the Lawn Tennis Association in 2005 to promote
