I almost set a new pb too but got the last question wrong... I thought I was being clever because tigers are also known to stalk humans before attacking
Teeeeeechnically the Grand Theft Auto series was first developed by DMA under David Jones. Rockstar games was created after GTA II was already out. Of course the answer is perfectly correct, but I love the fact that the Lemmings company originally made GTA.
Movies for teenagers - perhaps - but the most recent among these released in 1998. People in their 60s now were teenagers when Texas Chainsaw Massacre came out. As someone born in 1999: I missed the question for the opposite reason!
