I never played the first of the Fallout series, but played all of the Jagged Alliance games, which I felt were very similar in terms of turnbased combat with an isometric perspective, shedloads of loot to pick up and fool around with and a storyline, which was interesting but did not need to be understood or followed, that came second to the unbelieveably addictive gameplay.
I have been racking my brain for a game which has kept me interested for as long but can't think of anything, and I have played a ton of games in my 25 years, right back when Chucky Egg was on the Einstein computer.
Sure you can spend hours and hours playing RPG's or RTS games and I do, but none seem to come close to the fascination that I have always held with having a character silouette with inventory slots and a big backpack for junk which I may or may not have a use for, plenty of time to think tactically as it is turnbased, the gritty pixelated textures which were surprisingly detailed and satisfying and the anxious feeling of not knowing what the next segment of the map will have in store.
I think the fact that Fallout 2 was turn-based had a massive effect on my liking of the game and its replayability. The single reason I bought Civilisation: Revolution (PS3) was because it was turnbased. I think too many games rush you through everything and when you think back about what you have done, half of it is a blur and you might have missed a dozen or more things the developers spent a lot of time on, expecting the user to have the encounter and share the experience. Don't get me wrong, I love the adrenaline rush some games can give you, or the gurning facial expressions you find yourself making as a result of a particularly tricky scenario, but, for me, they don't seem to compare to having time to plan things out, ponder the probability of your actions and sometimes just being able to sit back and marvel at the game.
I am almost positive I will be using VATS 99% of the time for the sole reason I can pause time and contemplate my next move. I'm pretty sure I could never go back and play Fallout 2 or Jagged Alliance again now, which I'm sure many of you diehard Fallout fans can do and are doing to curb your lust for FO3. I think that is mainly because the boundaries for gaming have been broken and the bar raised so many times since those games were released that I need the latest technology to satisfy my gaming urges. I remember Lotus Espirit Turbo Challenge on the Atari and thought it was the best racing game ever, but it is nothing other than a vague memory now and I don't feel it was a particularly great game anymore.
However... I do believe Fallout 2 was one of the best games of its era, whenever the hell that was (I was young, I can't remember!), as I simply would not have played it if it wasn't, and even now with all the new next gen games pushing the limits of the hardware available it still remains one of the best games I will ever play. I also believe Fallout 3 will have that little something which all these other games have been lacking all these years since Fallout 2 and the Jagged Alliance games, for me at least, which will make it another one of the best games I'm ever likely to play.
I better get back to work now. End rant.
