The big one, or rather, two big ones, Dead or Alive's first cross-generation jump onto the PS2 ended up pitting it directly against Tekken Tag Tournament back in the early noughties, although it wasn't just a perfected fighting engine that had teenage boys enraptured worldwide. Nope, alongside a gratuitous gallery mode where concept sketches of ladies like Tina Armstrong had chest-heavy lady-cannons that could take down the Mary Celeste, you could actually dive into the settings and alter your 'age' setting - something that directly related to the size of the boobs in question. So naturally what did any hormonal 12 year old boy do at the time? Set it to 99, sit back and revel in the jigglery. Oh, and if you thought Tecmo had learnt their lesson since, they did quite the opposite for DOA 5, releasing a patch that mapped the motion controls of the PS3 directly to the overly-animated love-balloons on display. Although how you'd get a 12 year old's hand to move fast enough with boobs on the screen is anybody's guess...
