Telenet in its heyday maintained many subsidiary divisions; the most famous of these subsidiaries was spun off, reacquired and was ultimately absorbed into Bandai Namco. Telenet in its decline mainly released mahjong games, parlor games, and golf games (which they had a curiously long history with). In 2006, Telenet made the dubious move of licensing several of its classic titles for H-Game adaptations. In 2009, Sunsoft announced that it had acquired the rights to the Telenet game library.
Starting out as the development team responsible for some of Telenet's earliest hits on the PC-88, Wolf Team became an independent company in March 1987. Telenet retained a stake in Wolf Team, and brought the company back under its wing in July 1990. Wolf Team released many strategy games and visual novels for the PC-98, ports of 1980s laserdisc games for the Sega CD and RPGs for various systems, but their most distinctive titles were their action games on the Sharp X68000 and Sega Genesis.
By the time Wolf Team was beginning to develop the ambitious project that became Tales of Phantasia, Telenet was already in decline and unable to finance its production. An outside backer was found in Namco, whose Executive Meddling drove several members of Wolf Team away to found tri-Ace. After the game proved to be a hit, Wolf Team became almost totally focused on developing the Tales Series, with only one released game of theirs unconnected to it.
There's a bit of morbid trivia about Wold Team founder Masahiro Akishino: He founded J-Force, a video game company in the early 90s. Sadly, J-Force was beset with financial problems and development delays as a result of taking too many projects at once and ran into trouble with its clients. In 1994, Akishino went missing, and the company subsequently fell into bankruptcy. Most of the employees went to join the recently founded Idea Factory. Akishino's whereabouts remain unknown to this very day.
In 2002, Wolf Team became Namco Tales Studio, jointly-owned but with Namco holding the majority interest; its subsequent history is not included in the list of games below.

Telenet's overseas subsidiary Renovation Products published many of their games for the Sega Genesis, Sega CD and Super Nintendo Entertainment System in the U.S. from 1990 until 1993, when it was sold to Sega and all further releases were cancelled. (The U.S. localizations of Telenet's TurboGrafx-CD games were published either by NEC Technologies or Working Designs.)
