The new survival mode looks more like a chore than a challenge to me, having to eat/drink like every 14 real life mins to stay healthy or some crap, and no fast travel in a game with such a huge map, sure there are vertibirds later but that's way later, but it's really just a waste of time, the designers expected people to have insane amount of free time and patience to pour into this mode or some ****. I don't really see challenge in this, which requires people to think about how to overcome, but more like a pain in the ass.
Skill design is really lame in fallout 4 also, the no level cap design, again encouraging people to pour time into the game, gauss rifles won't even appear in the game unless the player spend like 50 hours leveling up, and makes it annoying for people like me to theorycraft builds because there isn't a level restriction, and weapon mods, one can spend many skill points and many int sacrificing build paths to unlock certain weapon mods only to find that a lot of them can be dropped and bought, and it's pure rng, idk what to even say about this system.
DA:I looks more like a dating sim to me, the first map is huge, then the rest of the maps were just dullaf, a lot of useless features like those points you get with nowhere to spend on, and again, no level cap, idk why people even like this feature.
I'm more looking forward to elder scrolls 6, although skyrim's combat wasn't exactly great either, my favourite game in this genre, or around this genre is probably kingdom of amalur: reckoning, the combat in that game is pretty amazing, and it has a pretty good skill tree system, open for theorycraft, too bad the art and story fall short.
Well the challenge comes from you not being able to manually save.
If you really play that game mode the other additions like no fast travel will make sense all of a sudden, goes very well with having to sleep to save.
I never got around playing more than the tutorial in DA2 but I probably should have tried DA:O before which I never even touched, sadly.
