Perhaps now, but at the time it wasn't. Some games, sadly, don't age well. But, I for one am glad that it exists regardless. It may not ever be a finished project, but the fact that we fought for this game to be made for over a decade and won, that itself is a miracle. Yes, perhaps it might not be as good looking back on it now, but what did we have to compare it to? AGDI? IA? Those games are also flawed, have some questionable writing choices and voice acting, and I don't see any of those stories being completed either. TSL at the time was the best of the bunch, and while it's sad that it'll probably never be completed and that is a disappointment, I at least can look at more fondly than most other fanmade projects, even today.
But then, what do I know about keeping to a schedule or even what constitutes good writing, given that the Quest for Glory fanfic universe I've been at for the past decade keeps stalling with me wanting to write new drafts and I actually liked the Sequel Trilogy of Star Wars which is a crime against fandom?
