Over the years I have managed to finish a few of my projects using Allegro. This is quite a rare accomplishment. Mostly one gets bored with a project before it even becomes something playable. The trick is to get over that hump efficiently.
Well, I didn't think it right to make a separate page for each of these so I'm just linking to my depot page at http://www.allegro.cc/members/Trezker/projects where they already have their own pages with screenshots and all that.
