Well Im going to go off on a little rant here....
Honestly I can say that Bethesda seriously f*$&@# up the Elder Scrolls series with Oblivion,but I will say this; it was a good,mindless distraction for about 30 or so hours,and it did have it's good points. Was it a RPG? Not really. Does that mean it was an abomination of God? No. Certain elements of that game would fit well into a Fallout game IMO. I stress IMO. No flaming is required.
Now here is my problem. I don't believe that they will mess with the atmosphere too much. I think that the Fallout feel will be there. I may be wrong,but who knows. My issue is with the dialogue. If they make it like Oblivion,where you have very few dialogue options I will be pretty dissapointed. I could go for a Morrowind style,but even that is kinda far off when compared to Fallout 1.
Now when concerning the "Turn-Based" aspect of Fallout I could care less. Honestly it never really made the game for me. I prefer the "Knights of the Old Republic" style RTP....if that makes me less of a gamer in some peoples eyes so be it.
To me the Turn based play style isn't what I'm looking for in a game,and to be honest very few people are. Which is why Bethesda isn 't implementing it into Fallout 3. Most gamers nowadays are looking for total immersiveness in a game. No one wants to wait for the other guy to attack,before they can attack. If the action gets to heavy RTP does give you a second to collect your thoughts,but it isn't absolutly necesary. That gives the gamer a choice. Realisim or tactics.
Now I know that Fallout has never been about realisim,but strictly speaking some people want to "feel" like they are in the enviroment without actually having to worry about the apocalypse. I am looking forward to this game,hoping that Bethesda doesn't screw it up to much like Oblivion, i.e compass,no dialogue options, and all together linear gameplay. Once again this is just my opinion. No flaming or hate-crimes are required.
