How big is the Galaxy and what type?

Simple question here. How Big is the Galaxy? In real life our own Milky Way is about 100,000 light years across<br />and 1000 light years deep on the galactic plane. It is a barred spiral. The milky way galaxy is not very big as galaxies go. But it is still huge. What type of Galaxy are we playing in? is it unbarred spiral, barred spiral, ring galaxy, starburst galaxy, a dwarf galaxy etc. And how big is it. Some Dwarf Galaxies have been observed that are only 100 light years accross  but most galaxies are far larger than our own. I dont even want to think about Clusters, groups or superclusters. It could boggle the mind. But, what size galaxy are you playing in?<br />
