Most of us, at one time or another, have done something we've regretted. Really regretted. Regretted enough to think, 'sweet Jesus, if only I could go back in time and absolutely NOT do that'. But, then imagine that you're given the chance to correct a calamitous error in your life - it's a complex decision because every action, every mistake, has consequences, often both good and bad; any one who's read Ray Bradbury's classic short story, A Sound of Thunder, will know as much.

So, if you had the chance to remove a key videogame series from the history of electronic entertainment, what would it be? What would the world of gaming be better without?

Forget about totally obscure titles, that's no fun - what's the biggest brand we can afford to lose for the good of games in general? And what do you think the consequences of its removal would be?

Can we, for example, afford to obliterate the Turok series of dinosaur blasters? The loathsome Postal? The silly Dragon's Lair?

Who goes? You decide...
