EVE New Citizens Q&A

Here's a size comparison video.

Not particularly informative game mechanics wise however. Did you have something more specific in mind? I have a folder full of bookmarked EVE videos.

Frigates are small fast ships

Destroyers use small weapons like frigates but they are a bit slower and take more damage

Cruisers are medium sized weapon ships. Slower than frigates and dessies but tankier

Battlecruisers are also medium sized weapon ships but more of a half way point between battleships and cruisers.

Battleships are slow and tanky. They do good damage but have difficulties hitting smaller ships.

Capital ships are their own thing. They are big and heavy and slow. I don't know of anyone that says that they are fun to fly and when you are in one you are kind of like the only female on a navy ship that's been at sea for six months. Everyone is trying to get a piece of your backside.

Super Capitals are flying coffins. They can not dock so once you are in one basically you can't leave until you hand it over to someone else or get blown up in it.

Damnit erg, stop being so damn helpful, making everyone else look bad.

Here is a video showing that you can in fact PVP effectively with very little SP.
