Don't worry, I don't mind suggestions. I don't think of them as something I have to do but rather something that someone would like. But there are a couple of things I have to keep in mind when
personally emulating a game (i.e. once the XL Engine is mature and Open Source someone else can work on this too, as several people haven mentioned):
* I have time (i.e. meaning no "ports" that are not currently on the list until at least 2 of the current projects are in Beta or beyond - most likely DarkXL and DaggerXL).
* It's a game that I personally enjoy. All the games in the list are games that I'm a fan of and wished for ports in the past. This last point is absolutely required for projects like these, unless you're getting paid big bucks. You spend so much time learning the intricate details of the games that if you don't enjoy them, you'll go crazy.

Since I'm not planning on releasing the XL Engine source code until it is mature and clean, it'll be a while before other people can start porting stuff. While many will disagree, I don't want people basing their work on sub-optimal code that will probably change drastically. I will, however, be releasing all the scripts and game code much sooner then that - once a project goes to Beta (or sooner).
