I still own a game called Universe, character creation is a nightmare and I never understood the rules, it remains unplayed and IMO unplayable.
I’ve never liked Traveller 2300 aka 2300AD. Love the background, hate the rules.
FASA’s Star Trek shows why percentage skill based systems don’t always work. “Standard orbit Mr Sulu” [roll] “Er, I’ve failed Captain.”
HeroWars/HeroQuest by Issaries. I love Glorantha, I want to love this game, I want to play this game, I can’t. Why? [That’s a genuine question btw, lots of people think it’s great, but I can’t cope with it. Perhaps I’m too simulationist.]
DnD 3.0+ Sorry but it’s much too complicated for me!
And, the worst (though I’ve never played it) must be FATAL. The website says ‘F.A.T.A.L. is a role-playing game like no other.’ I’d certainly agree with that statement. Unfortunately, it goes on to say ‘It is the goal of Fatal Games to astound and thrill those who seek a role-playing game based on historical and mythological accuracy, realism, and detail.’ This frankly is bollocks, this is a mean minded nasty sexist game with no basis in history, myth, accuracy, realism or detail. I once read a review which said (IIRC) ‘Their tagline is ‘FATAL GAMES, where the dice never lies’ I didn’t know that you could buy dice with ‘this game sucks’ written on every face.’
Finally, I’m a Dr. Who fan (of the series, not the game) I don’t remember FASA’s Dr. Who game (it sounds a bit like their Star Trek game). Dr Who Time Lord was much better. But if the game is structured like the TV series, then what’s wrong? I loved the James Bond game, because it worked if you acted like Bond, go with the flow, let yourself be captured by the bad guys! I know lots of people who couldn’t cope.
