Uhmm... not at all true, though?
Man, this makes me feel old. We've had real-time RPGs well before Fallout 1 came along. Fallout was actually a niche game at the time it came out - it was refreshing to see a turn-based game like that with "modern" graphics. Diablo came out before Fallout, that did just fine in real-time. Ultima was doing real-time gameplay (and in 3D) before Fallout 1 was released. The old D&D dungeon crawlers were real-time. Going way back, I remember playing Dungeons and Dragons on my Intellivision, and that was a real-time game as well.
These were not technological limitations. These were design choices. It's... man, I gotta be honest, it's kind of flabbergasting. I mean, hey - I can dig the new Fallout games. I'm absolutely stoked for Fallout 4. I don't have just one sort of game that I insist on playing and expect all other games to cater to my whims (and it's been a good couple of years for turn-based gaming.) But it's like a tech tree - you've got real-time stuff on one branch, and turn-based on another. And then people keep saying that all gaming technology is actually progressing along a straight line to some inevitable Platonic Ideal. It's just provably false. I mean, we all have preferences (which on this forum gets forgotten every second page.)
Anyway...
What I like about having meaningful choices in how I build my character, is that without any consequence, without my character being able to do some things at the cost of other things, is that otherwise I'm not even making any meaningful choices - I'm just progressing my character to the inevitable sameness. I just don't enjoy that philosophy as much as others - at least in an RPG.
I mean, the Arkham games have experience and skills to pick from. But you're really just participating in an extended tutorial. You don't want to overwhelm the player with special moves all at once so you parcel it out behind the RPG mechanics - you're always going to be Batman, and Batman is always going to be awesome at everything, but you learn the advanced mechanics as you play and choose which to unlock next. Mind you, I adore those games - but it's not what I'm looking for in a roleplaying experience.
If there's no consequence to any choice I make, then I'm not actually making any choices. Sure, I can RP that I'm actually specializing in meaningful ways and creating a unique character, but I'm not actually doing so - it's an empty challenge (and I'd prefer a game that isn't, quite simply.) In Fallout 3 every character was the same by the end of the game - every character I made in Fallout 3 was going to be Batman. I could pretend that my Batman was different than your Batman, but at the end of the day we were all playing Batman.
So... back to topic, that's why I'm hoping that doubling-down on Perks can add some more individuality to my characters. I can at least then choose between Micheal Keaton Batman and Christian Bale Batman.
