Look, I'll do you a favour and just tell you straight up that this is unacceptable. I registered just to post this.
Unfortunately a developer sometimes has to make difficult decisions based on his/her/its limited budget. It'd be nice to have an unlimited funds and an unlimited timeframe to complete a project (Duke Nukem, anyone?), but welcome to Reality™, where "Stuff Just Don't Happen That Way."™ BW made a decision to not support widescreen based on the design of Eschalon's engine (which is his first major foray into game development/programming) and the time/cost to rewrite said engine to support said feature. That's just how things worked out. If he had "started doing this with Book II," Book II may well have not been released anywhere near when it did, if at all.
You're not doing anyone a favor by calling BW's decision "unacceptable." As a matter of fact, if you're a "content developer" and have any idea how the indie gaming industry works, then I find your remarks quite "unacceptable."
I'm one of this series biggest fans, don't hate for telling it like it is.
You'll have to excuse me for telling it like it is and calling BS. The fact that you "registered just to post this" speaks volumes against you. Enjoy the series for what it is, not for how you want it to be.
Oh, and welcome to the community.
