Well the money saved by not buying a SGX and its three supposedly great games will buy you Spriggen 1+2, Kaze Kiri, Star Parodia, Lords of Thunder, Bomberman '94, Gate of Thunder, and a bootleg of Sapphire, all of which a far better than any SGX game. I think that a lot of people would agree with me when I say that none of the SGX games even crack the top 20 of PCE soft.
I think that if you have infinite cash (and space) the SGX+CD is great, but for the more practically minded it isn't even worth the space it wastes. This goes double for people just starting out like this guy is. Like I said, I fully intend to buy a SGX someday because I like NEC stuff, but I fully realize that there is no point in it. The most useful feature of a SGX is its ability to play non-SGX HuCards.
