What 2D Linux Game Engines are out there?

I ask this because I'm looking to make some old-school-style adventure games (Think of the mid-90's era for LucasArts, Interplay, and Sierra)

I would greatly appreciate if anyone could point me towards a portable, lightweight engine licensed under either the GPL or a BSD license. It would be nice if the engine could easily be tweaked to do the following:
-Creation of a custom in-game interface.
-Multiple cursors with each cursor serving a function. Right clicking would change the cursor. Most adventure games have Walk, See, Do, Talk, and Inventory Item.
-Control a single player character that is capable of audibly interacting with NPC's.


I'm sure that, given enough time, it would be possible to achieve this oneself. I am looking to write portable, free games. My goal is to improve my writing, drawing, animation, and programming skills. If anyone can help, I'd appreciate it.

What did Sonic the Hedgehog on the Sega Megadrive use? I loved that game when I was, uh, younger. That spinning hedgehog moved pretty drokking fast.

Heh, no idea. Some proprietary engine, I would assume.

I'm currently looking into PyGame. Currently I'm using Dr. Python as an IDE, but if anyone else has a suggestion for a good Linux PyGame-compatible IDE, I'm willing to consider trying it.
