The thing about Destiny vs Warframe vs Division for folks is this:
Destiny has zero depth, all you need to do is find a gun you like, and get your Light Level as high as possible. In d2 you can look at anyone else in the open world, see their LL and you will know what that person can and cannot do in the game.
Warframe has so much to keep track of that its actually daunting. No one is exactly the same, ever, fucking EVER in the game. There are 851 mods in the game, each frame has 10 (i think), each weapon has another 8 (maybe 10? its not equal), each companion (pet) also has another 10. There is so much customization for the player to think/ worry about that spreadsheets exist
Now these are two extremes of the game depth scale, rain puddle (destiny) to Marianas trench (Warframe).
Division lies somewhere in the middle. Plenty of build options, plenty of weapon mods, plenty of "supers/ equipment", so that you don't really know what another player is capable of until you see them in action for 20 or so minutes. (some times not even then).
That being said though, I don't think you, Lee, will like either game. Which is fine, but like Rob said, we need to be really honest here with enthusiasm and our willingness to forgive Bungie for fucking all of us over the last months. The company that brought us Halo is gone, it has been replaced by an activision clone, that is also now taking money from a chinese company (NetEase) in the form of $100 Million to explore new gaming options...... I can theorize what that means, but i dont think I should. I will leave that to you guys
