This amuses me. Given how much shit people gave/give FO 4 for being a buggy mess, the idea that they are rebuilding the infamously buggy NV with that engine, and this is lauded as an improvement. I just....it just makes me smile. Guess it's not such a shit engine when it's lightyears better than the shit NV engine, and will give people a chance to try and play that game, in a state that is even remotely stable.
As to the game itself, personally don't care. I really don't like NV, and found it to be incredibly boring, so boring in fact, that it took me 3-4 attempts of restarting the game, to be invested in it enough to want to finish it. I'd find myself sort of zoning out, running through the endless brown/orange wastes, and suddenly blink out of a fugue and be like "wait...what was I doing again?" I'd lose all emphasis to play it, and just stop playing.
