Cyburn writes : "The public demo for Super Smash Bros that was released back in early September was quite limited, especially in terms of character/stage selection. The EGX booth demo, on the other hand, provided a much more generous selection of characters and stages which gave players a better impression of how the full game would be.
The rules were restricted to 2 minute matches in the demo, and you play against CPU characters drawn from all the characters available from the start (all set at level 3, which is accessible to players who are new to Super Smash Bros). The choice of characters range from representatives from the staple Nintendo franchises (such as the Mario series) to more niche games like Fire Emblem and Xenoblade. This give players a lot of choice and chances to explore all the moves with each character (hence adding longevity)".
