My little cough has now grown into a full-blown fever. Lucky me :P

Indeed, in Quake 2 the engine has been enhanced with many new features, which allow for a more varied experience. Even if the subject matter is not related to Q1's Lovecraftian atmosphere, the gameplay definitely has Quake written all over it. The biggest change is the inclusion of objective-driven levels, which can be pretty fun (especially if something goes wrong and you have to think of some other way to complete the objective). Most of the familiar old powerups are there (except for invisibility), and most of the weapons are based on Q1 (but with a little more realism). Ambience has been improved as well - there are often explosions and other sounds of warfare heard in the background, or you hear messages from the command ship.

Overall, you can think of Quake 2 as an enhanced version of Q1's idBase levels.
