Your argument is pretty weak if you're having to use games like this to furtger it. No one wants to play this game right now, much less in 10 years.
This isn't a problem. You didn't care about this game yesterday and you won't care about it tomorrow. You only care about it today because it pushes your narrative.
You know, I really dislike people who have your 'viewpoint', where you can't see past the end of your nose.
There is no narrative to push other than the preservation of our medium. There is no defence, none whatsoever against losing games forever. No matter how bad, how unpopular, losing a game should be a tragedy to all gamers.
My argument is made more strongly for standing up for games that are supposedly bad. We shouldn't pick and choose what we preserve.
Furthermore, You can't have been gaming longer than 10 years if you believe a crap game is crap forever. The jank that has been published over the years sometimes turns into gold. Deadly Premonition is one of the lowest scoring games of all time, yet, is one that is beloved by most of those that played it.
And really, if you think publishers taking games out of the reach of games isn't a problem, then there's a high probability that you don't really care about gaming, you just do it because you have nothing else to do or you fail to see, understand or comprehend what a slippery slope is.
