Tip for Classic finished in about 19 days - You will need to have a THOR Ramjet, Whirlybird 512, max fuel, ramp height and ramp length, and just cast iron and a bobsleigh. Try to keep your average flying level about 300, and use your boost a LOT at the end. That is my tip.
@Nemas, do you have an ASUS computer? I have one, and it freaks out with EBF3. It wears off over time, but if you want your party to stop, tap the key again.
Absolutely fantastic. You can talk to NPCs, engage enemies without them engaging you into battle, and a currency like most games, useful for (my favorite!) FORGING. This would be the best game EVER in multiplayer. Can't wait for the 4th, but for now, this will do!
