In one of your last posts you said you wanted your level 60 character to be different than someone else's
That won't happen without loot collection and deep crafting system
And this proposed system isn't at all like Diablo... and it certainly would not allow for grinding - but rest assured that keith has ideas that go beyond this ;P
In the same way that my 20 hour level 8 AI war game is different than yours. You can make meaningful decisions that differentiate you without hunting loot.
Taking research labs and finding buildings like datacenters and caches is the AI War equivalent of random loot 
Actually, no it isn't

I think you should clarify what grinding is before you announce that every reward system in gaming is grinding

.
The act of grinding is repeating yourself over and over again, often for marginal gain. In AI war, different situations are kind of like puzzles that you have to adapt to. A lot of those puzzles are optional. And just like in chess, the board almost always looks different at some point. So that is not grinding. In Valley (and this has been said many times), people are feeling repetition. You jump around using the same spells over and over. I used the same 2 spells for the first 10 hours. Every once in a while I would find some marginal treasure, but it was definitely repetitious. That's grinding. I don't want to continue on that path where we do the same thing over and over and definitely not for some avatar graphics. The gameplay has to be meaningful. I don't object to decorating the character, but if the object of the game is to repeat yourself over and over for a awesome avatar, that's grinding, that's boring, and that is what I'm objecting to.
I want the game to offer some intellectual stimulation. If this was Zelda, we would have a story and an overlord. Over time, you unlock all kinds of abilities that allow you to explore even greater dungeons. Eventually, there is the moment where you finally take on Ganon. We don't have that here. We do have some bosses, but we don't have these handcrafted dungeons with bosses that reward us with some ability to progress to the next dungeon. We just get some shards to make version number five of some spell. I was hoping that the city building was going to offer that piece of intellectual gameplay, but maybe it's not. Maybe people are just going to be hunting down cartoon helmets

That just seems like a simple goal to settle for. That's all right once in a while, something like Diablo or Titan quest can be fun, but I didn't think this was going to be that game.
