You state that there a ton of problems with Minecraft and that it is not worth the money people pay for it. You also state that you in fact play Minecraft and have fun with it. My reading comprehension is fine.
I don't think people here are saying Minecraft is the best game ever. But for a sandbox game it is quite unique in letting you do pretty much anything. Yes, it has flaws but so does for example WoW, argueably one of the best grossing games in history. I don't fully understand your statement, you say Minecraft isn't going to win any awards then follow that up by saying Minecraft is winning awards because people can't be objective. So..how did they win, because everyone is a MC fanboy?
The original game was coded by one person and was designed to be a simple sandbox game where you MINE and CRAFT, hence the name. Yes, they could funnel money into making it look better and run smoother but a lot of people as I've said prefer the graphics of the game currently. I didn't play with legos cause of their awesome graphics. I played with them to build. I will yield the point of the game running poorly but honostly, do you need 120FPS for a game like this? On a FPS or MMO, yes, those FPS are handy but on this type of game, hardly necessary in my opinion.
I don't think it was specifically stated but as I said, a lot of people like the graphics the way they are.
In most instances I'm sure you're right. They decided to add it here but not make it a focus. I do not work at Mojang so I can't say why they chose to add it but it is easily seen it's not meant to be a focus.
At this point I'm fine with the game as is. But that's just me. I play it rarely now anyway.
