I've been wondering if Fallout 3 lives up to the expectations set by Fallouts 1 and 2. Oblivion, quite frankly, was a downpoint in The Elder Scrolls, I'd like to know if Fallout 3 would disappoint me or if it's still pretty good in terms of complexity and RPG elements.
It will depend on what you're looking and hoping to get with this game. It's clearly inferior to the first 2 Fallout on the scenario, which is one of the lamest I've ever been through, the writing which goes from terrible to just okay and with some very rare dialogues which are actually good. However, if you liked the Elder Scrolls main strengths, which are a huge open ended universe filled with a lot of stuff to do, you'll like this Fallout 3. It also has the quality of being far less generic than Morrowind or Oblivion with a lot more specific places. But it's also far more inconsistent with still-working computers in totally ruined environments, DC ruins in a remarkable state of conservation for a city which is supposed to have been hammered by its fair share of nukes even still featuring a lot of working restrooms, water sources and propaganda poster in near perfect state albeit a bit decayed. Well that's good for a Wasteland 10 years after the war, but it's consistently said it's been 200 years... That being said, energy weapons, power armours and other highly advanced stuff remains rare until you progress the main quest enough to see place and people which truly have some reasons to have this stuff. So you won't find raiders equipped with plasma guns and power armours.
You'll find some complexity in the large number of weapons available, that you can manufacture your own weapons with the proper schematics (and the Shiskebab is a great invention) and most of the quests features skill, reputations and other various kind of tests opening new dialogue options. The downside is that sometimes, it's just used to skip parts of the quests and thus, skip parts of the game content (or at least, directions and the idea to go there), which quite not the way I would like to use my character speech skill but it's quite consistent with what you'll be asked to do (in this case, irradiating yourself to a high level). One of the main strengths of the game is that you can wander in the Capital Wasteland and actually find interesting places and even be given some good quests very reminiscent of the old Fallout in their design or even more rare, their writing. You'll have to avoid as much as possible the main quest, which as I've said before, is the worst part of the game and to be fair, the worst and dumbest main quest-line I've ever played through. That's a total disappointment and what I really call a critical miss from Bethesda.
But once you decided to do the side quests and concentrate on doing what you want, this is where this Elder Scroll: Apocal... ooops, Fallout 3 really shines. Most of theses quests have many ways to be solved and depending on how you do them, you might have as a reward 50 caps, some interesting perk or an enhanced Plasma Rifle (pile of green goo in case of critical hit). One of them begin in the very uninteresting form of a fed-ex one to evolve in a kidnappers hunting (with three possible places to find them without anything more than markers on the map) to finish in a possible reconciliation, slaughter or maybe even something between these two extremes. In another one, you'll have to choose between 3 or 4 ways to handle a little problem with a very well known character of the Fallout franchise each ending in different rewards ranging from an useful perk to a Power Armour. Or you might just be asked by a women to collect a lot of glowing Nuka Cola bottles to discover that the man next-door would like to have these bottles to seduce the woman. Or you might want to choose between helping those poor ghouls to enter this nice upper class and heavily guarded tower to discover, that, erm, these ghouls were not as helpless as they might have looked and begin to be quite elusive when asked on the whereabouts of the previous owners.
To sum it up, you'll find most of the fun and the interest of the game in doing everything save the main quest.
Provided that you play on very hard difficulty mode, the Oblivion with guns stuff works pretty well after all. You'll actually find a very challenging game in the beginning, which has sometimes forced me to use drugs (which I've never made in Fallout 1 or 2, but maybe it was because I used the 10 AG 1 CH 1 LK trick to ease my way through the game) and pushed me to cleverly use the VATS to tactically disable my opponents (since they had too much HP to be killed quickly). This also has the effect of consuming an awful lot of ammunitions and stimpacks and I remembered a bit the good old days of System Shock 2 (where you never had enough stuff to feel really comfortable to handle the next fight but happened to be just enough to beat the game). Like the old Fallout, the more you progress, the more you'll have stimpacks, ammunitions, powerful armours and weaponry so in the end the fights become far more easy and far less challenging but you still might be able to die thanks to critical hits or mishandling the fact due to overconfidence.
But for me, it's like every Bethesda game: a game marred by a lot of congenital flaws which manages somehow to be interesting thanks to its technical abilities and its open-ended world.
I'm just still startled to see that Bethesda doesn't even seems to be willing to fix their own flaws in writing and scenario since a game combining the qualities of a Fallout 1 or 2 and Fallout 3 would be pretty awesome, to say the least.
