Video games

With a franchise as large as Transformers, it is unsurprising that there have been many video games.

• Transformers: Convoy no Nazo (Famicom)
• Transformers (Commodore 64)
• Transformers: Battle to Save the Earth (Commodore 64)
• Transformers: Head Masters (Famicom Disc System)
• Beast Wars: Transformers (PC, PS1)
• Beast Wars: Transformers Transmetals (N64, PS1)
• Transformers (PS2)
• Transformers Tataki (PS2)

Optimus Prime also appeared in a Japanese Beat-Em-Up with a weird cast of characters (Mostly from Konami) called Dream Fighters TV Mix I believe.
