Yesterday I came across some QBasic posts and found about "Black Annex" game which passed Steam Greenlight and was actually written in QBasic with more than 12.000 lines of source code.<p>Anyway, I am curious about popular and/or relatively successful projects that were written in programming languages which are not considered perfect fit or usual choice by other developers (for that particular application) or simply not modern enough?<p>It can be from any segment: console, web, GUI, server-side, game etc.<p>Thanks.
