I'd like to add my voice to that of Kavonde in saying that Fallout 3 was ultimately a big disappointment.
I am a big fan of the originals, and I am a gamer who mainly has a preference for games, that I'm sure many other, most probably from the console side, would consider slow and too indepth. I like RPGs and strategy mainly I guess.
That said, I play FPSs but they generally spend the shortest time on my drive and usually only get one playthrough (I'm not a multiplayer at all). And there are exceptions, the Half Life series being a prime example.
But to get back on point, while initially entertaining, Fallout 3 became for me a dull, routine slogfest. It failed on both counts as an RPG and as a FPS. The world, while beautiful to look at is ultimately pretty vapid, populated by inane characters, voiced badly, and with unrelatable motivations. The plot was again fairly subpar, topped off at the end by the rediculous unavoidable main characters death, even if you have the completely radiation resistant mutant companion.
As an FPS, it became obvious that VATS was just a way of covering up the fact that the engine was completely unsuited to running and gunning. Compared to any dedicated FPS (Crysis, Halo, Brothers in Arms) it's amaturish. A prime example being the weapon firing points. They didn't actually fire from the gun muzzle but from some arbitrary point on your right. Meaning any attempt at close cover firing left you emptying your clip into a wall. And VATS went stale. Fast. Waiting 5 seconds for the camera to release control after every kill, and the blatant systematic cheat that almost completely removes any damage inflicted on you while the camera maintains control. So while you watch a ragdoll's body being obliterated in slow motion, you happen to glimpse from the corner of your eye, your character taking a full plasma burst to the face. But when you're back in your body, oh no, it just gave you a nice smooth shave.
It was just full of lots of small, and not so small, and some rediculously obvious, flaws. I finished it, and eventually got and made good use of the level cap remover so it definately wasn't a case of not giving it a chance (Nerdfury - yup, I guess I'd have to agree it was permanent exhaustion). And this is over a year since my last game and the problems still stick in my mind.
It does disappoint me that very few mainstream reviewers seem to reflect this 'opinion'. I appreciate the weakness of that statement, opinions being opinions, but jebus, I'm not that different in my expectations am I?
I'm really looking forward to Obsidian's take on this new current Fallout mutation as I'm sure they will fix much of the 'fleshing out' problems but there seem to be some flaws, engine based at the least, that they won't be able to change.
I hope I'm wrong and I hope this doesn't come across as purist ranting as mentioned a bit back. I'm not advocating a return to isometric, just a satisfactory implementation of whatever method succeeds it.
Simple summation; in so far as two completely different types of games can be compared, I felt both 1 and 2 were simply much better games/experiences/stories than 3.
P.S. I wrote this before reading all the comments so I'm glad to see a few people who seem to share my viewpoint.
