Hmm.....true true! You can do that.
As for me, I still need to get a job and if I do, I'm saving it all for a DS, 358/2 Days, (possibly a used The World Ends With You), a BBS, and FF: Dissidia but people kept telling me to buy all of it seperate and get the other later on.
That works but I'm kinda impatient unless if it comes to saving money, then that's different as I'm weird like that. XD But I rather save my money for all those game and get all the games together and such, so I don't have to WAIT to buy one or another because that annoys me if I have to get one seperate and if I save money for all of it, it's worth it. XD At least for me...since it's time consuming in a sense.
