Multiples

[fahlim003]

I've gone out of my way to get a second copy of a game once: Gran Turismo 3. You might say different region versions of the game aren't applicable since there can be actual game play distinct/differences, and with GT3 there is. Otherwise, I'd only have my original US copy and not the Japanese one.

I get most of my multiples in lots, too, but I have no reason to keep them. It's the same with games I don't personally enjoy; they get resold to go towards something worth more of my time. I will say, though, anytime I see a game I already have I have to question if the time spent trying to sell it or the funds recieved from the sale are more valuable.

I will by buy a multiple (1) if its in a lot and there's other items or games I want anyway (2) if its a game I really like or want a back up for in case of failure and I usually only do this with my absolute favorites (3) If its condition is an upgrade to the one I have.

A perfect example of number 3 happened just yesterday - I found a CIB copy of World Carmen Sandiego for the Genesis. I already own one but both the cart and manual are in much better shape and this new copy had a nice crisp poster included. Now I'll probably put my older copy up for sale because I don't see a need to keep both.

If different regional versions count as duplicates, then I have lots of those. In most cases, I had the Japanese version before the US version, sometimes before there was even any announcement of a US release. In general, though, I usually only get imports that never got a US version, since if there's a US version, I'd prefer to get that. Sometimes even that plan fails, though, like if I buy a Super Famicom game that only came out in Japan, only for it to finally receive an official localization on DS or something. Since I still haven't played the games, I kinda wish I never bothered to buy SFC games like Dragon Quest VI and Shiren the Wanderer, now that they're available in English on DS. Oh well, they're in my collection now, so I'll just keep them. Maybe after whenever I play the English releases, I might want to replay them via the Japanese originals to see all the differences.

Ausiie2B put a good one out there, Save Files! I have three copies of Dragon Quest Monsters Joker and two copies of DQMJ2 as well as both games loaded on the R4. You can't imagine how frustrating it is to have to buy a new copy of a game if you want to start a new character and actually enjoy the story again. I don't want to wipe out my uber-powerful custom team that has literally hundreds of hours invested in it, so a new copy must be purchased. One of the few times I think ANYONE should have absolutely NO qualms about ROM usage.
I have TWO copies of Terranigma. One is German in a giant Chrono Trigger-sized box with a full strategy guide. The other is a PAL english CIB that is standard sized and sits nicely next to my PAL Illusion of Time CIB, even though I have a CIB Illusion of Gaia for use on my NTSC console.
I have a CIB Kiwi Kraze, but because the first time I ever played that game was on an arcade machine as a child it didn't feel right not having it be called The New Zealand Story, I imported the CIB PAL NES version from Ocean. I also have it on PSP and DS, and on Taito Legends for X-Box and PS2.
I couldn't even tell you how many versions of Final Fantasy titles I have, but with PSP having nice graphics for the remakes of 1,2, and 4 plus bonus content, you've got to get them. I'm not fond of some of the name changes; I'm looking at you Kary from FF1 in particular. Also it's TERRA not TINA for 3/6 conversions.
I have Bioshock Collectors Edition for X-Box with Soundtrack and Big Daddy. I have a sealed PS3 Collector's Bioshock 2. I have non-collector versions of both to play on my PS3.
Kirby, Mario, Samus Aran, Simon Belmont... There's no way you can't get duplicates of some of their adventures if you build up a semi-serious collection. In short there's no all-in-one "perfect" example of almost ANY game out there, so you get duplicates to enjoy different aspects of the TOTAL experience that is offered up to you in pieces over time. Look and see how many Double Dragon games it took for Retro Gamer to review and they ALL had their own faults. Noone got it "All Right" yet and this is how many years later!?! It's just one of those things... I also have 5 copies of Super Mario 64, 3 NTSC, 1 JAP, and the DS remake which is the only one with any different content. No particular reason to own that many, especially with 4 save slots per game, but they aren't going anywhere. Maybe I'm strange, but I think it's normal to acquire duplicates that you don't intend to get rid of and we all do it for many different reasons.

I'm completely for getting other-region duplicates when there's a reason to, like Dynamite Headdy's JP version having a story and being easier (aka POSSIBLE) or JP Castlevania 3 having that sweet sweet VRC6 music.
