Rotom are capable of possessing any device which runs on electricity, and although they are best known for haunting televisions, they have received a great deal of attention from the video gaming community with their occasional penchant to possess consoles and handhelds alike. A Rotom's presence in these systems prevents other games from being recognized; instead, the game system will play a single, bizarre game of the Rotom's own devising.

The games differ from Rotom to Rotom, at times taking inspiration from existing titles (most often those their haunting interrupted) but Rotom are creative pokemon who are just as capable of using board, card,or dice games to build their strange universes. The graphics these Rotom create are impressive, often using capabilities otherwise impossible for the system, and the games themselves are noted as much for their extreme difficulty as for their often disturbing storylines. Most gamers who encounter these games attempt to play them, although the lack of any walkthroughs or strategy guides combine with the bizarre rules the Rotom devise to create a mighty challenge.

With enough time and practice, virtually any game is beatable, and a Rotom will only cease to haunt a system once the game they created is finally defeated. The Rotom is then captured as surely as it would be by a pokeball, and other games can finally be resumed.

Those gamers bored by the challenge of a Rotom-possessed game, or who give up in frustration or can not wait to play other titles, soon find that their systems sell for more than when they bought them. Not only is catching a Rotom through battle even harder than catching one through video gaming, but many gaming enthusiasts are willing to spend vast sums to play the challenging games which only a Rotom can provide.
