OXM - Releasing a demo is a high-stakes affair. If the demo's excellent, pre-orders may double. But if it's merely good, or even excellent but a little too substantial, players may feel they've had their fill long before the finished article hits shelves. And a bad demo? A bad demo can be the kiss of death. Just look at now-defunct GRIN's Bionic Commando remake. It's not a perfect game by any stretch - po-faced and clunky, with an uneven learning curve - but it's a lot better, a lot more interesting than the shonky multiplayer trial makes out.
