If we're actually going to start discussing ds, here's my take on him and his arguments. He's a jealous incompetent who can't stop tripping over his own failures, the result is his criticisms are mostly projections of his own failures in game dev. He pretends every bad review he gets is from an SC fanboy meanwhile he produces hot garbage an experienced dev would produce faster in a week of work in unity. He charges hundreds of dollars for nonfunctional weapon packs and other nonsense, the only difference between SC's price model and his is that he cant actually get anyone to pay for his text blurbs describing weapons, since he cant even afford to make decent jpgs for them. It's important to realize that since a few years ago dsmart has staked his own reputation or whats left of it on SC failing, once someone does that they can no longer be trusted to change their opinions or provide reasonable argument with new information, no matter what SC does he will continue saying the same things.
Some would argue his failures make him qualified to criticize SC, i would argue they demonstrate he is stuck in 2000 era development strategy and hasn't been able to move past it. The lumberyard stink he made is a good example of this, the way upgrading and "changing" engine components works is very different for a large studio with resources to actually write their own versions of engine components, most even AAA games simply have to rely completely on the engine as a self contained core, but SC has the budget to rip out pieces of the engine they dont like and do it their own way. This is something DS has never been able to do and so he doesn't believe its possible or understand why changing to a lumberyard core didn't take them more than a few days of skilled engineers working.
My point is that no, it isn't worth checking dsmart's arguments. I would put more weight in random stranger's opinions, at least there's a chance there they aren't coming from a bitter washed up idiot better known for being a forum warrior back to the usenet days than any game's he's made.
