Slow framerate, crashing, freezing? These were things that weren't present in FO3 at launch? Man, I'd LOVE to have played the version you played.
A young development team, sure. Obsidian has been around for 10 years (and when taking into account the fact that Obsidian was initially just BI guys, they have been around for closer to 20 years). Developers like that don't get crappy contracts due to Metacritic reviews. If we were talking sales, I'd agree, but we aren't. We are talking review scores.
Well, guess what, those issues are also present on Skyrim. Which you can expect with a game this size, which is understandable if you understand the many things that have to be loaded on any given cell etc. Most people expected that. I played FO3 on the XBOX and rarely has those issues.
What i'm trying to say on my earlier post is that the things that may have prevented F:NV to get the GOTY were the bugs that exclusively NV. Things like their revised karma/ rep system , which if it bugged, affects certain NPCs which then in turn affects quests, which then broke those quests for example. FO3 also has bugged quests, but not to the extent of NV because of ...the example i stated .
Then there is also their revised armor ratings, revised weapons damage, companion systems etc. These were all Obsidian idea. And not to mention the bonehead idea of actually ending the game. Have they not learned from the fans outcry before the broken steel DLC? as a matter of fact, the VERY FIRST mod for NV was the one that allows you to keep playing AFTER the main quest. That should be an indicator of what the fans really wants.
Let's also not forget one of the major complaint about NV ( aside from ending the game)...which is the lacks of enemies. There you are with your heavily modded guns and armors...and there's NO ONE to shoot! it reminds me of the old saying about plays or movies...if you introduced a gun on the 2nd act, you better make sure somebody get shot on the 3rd act! This one fact really took out the fun from the game IMO. So, in my opinion all these things that ultimately caused them not to win the GOTY ( i didn't even know they didn't until you mentioend it btw)
Believe it or not, people can get over frame rate issues and occasional crashing/freezing as long as they can reboot and continue playing, but if there is a broken quest,forked weapons etc that can't be fixed with rebooting your console...well... and those framerate issues etc are also present in MANY other games and not exclusively Bethesda.
As far as their contract with beth,i still say is normal for Beth to have anybody working for them,regardless of experience, to have the same standards as them. be it in terms of sale or critics.Nobody holding a gun to Obsidian head and force them to sign. They obviously thought they can met those standards and they failed, so...
Ps. I may sounded like i hate FO:NV, but i really didn't. i freakin' LOVE the game!
