Hm, curious how you failed to mention Mass Effect 2, but you mention an ancient Deus Ex and make up stuff about Borderlands, seriously Borderlands, the best fusion of RPG and FPS ever made with not a single thing wrong in the FPS aspect?
Source?
With which game would you compare it to as to its extent? Does it just barely cross the threshold of meriting the label "customization"? Is that the full extent of the RPG aspect, no inventory, injury mechanic and weight like in S.T.AL.K.E.R.?
I mentioned Deus Ex because it's otherwise a great FPS/RPG hybrid. Regarding Borderlands I didn't really like the feel of the aiming (then again there is somebody complaining about the aiming in every game so I realize thats hugely subjective, I don't really like the movement/aiming in unreal engine games in general), combat just didn't feel visceral, there was not enough variety in it. It just felt like clickclickclick, sorta like Diablo... didn't provide me with the adrenaline rush of old school id games, or the tactical, measured gameplay of Stalker (which did have light RPG elements, so I guess thats another good example of those games). Also there was a lack of variety in enemy design. This is one pitfall Rage can fall into as well, and I hope they avoid this. A great thing about old school id games is that there were many different types of enemies, and you had to use diffferent weapons/playstiles to be really effective against them. Simple but effective game design.
(sidenote: why is that every thread in this forum devolves into an arguement about other games?)
My point is simply that if I wanted to play an action RPG I would play an action RPG (and I will because I like them). But I want different stuff as well, pure shooters for example, because I don't just want to play the same game in a different setting all the time. But if action RPGs are all you want there are many action RPG games for you to play, and there will be many in the future.
And the weapon/car upgrade stuff has been mentioned in countless developer walktroughs/interviews, and has been talked about in this forum. In the interviews they basically said the RPG aspect of the game is improving what you have, and gathering new equipment and not filling up stat bars.
