I could order a PS2 right after writing this - no problem at all. Why am I not going to? Because at the moment there is absolutely nothing going for it, and I do not want over-priced, under-performing versions of games that are already available. It has potential and I may get it one day (when Sega has some games on it) but as yet no-one has delivered the promises made in spring 1999.
However, the Dreamcast is incredible: it generally has better graphics than PS2, internet access, email, fantastic online gaming (Quake III, Phantasy Star...) and four player capabilities as standard without paying out for a ... multitap. But it's the games that matter.
There are so many DC games that just ooze quality and have clearly had so much attention lavished upon them during development (MSR, Shenmue, Jet Set Radio, Quake III, RE Code: Veronica etc). PlayStation developers just can't seem to put the same soul into PS games. PS2 DVD playback has been getting average ratings in DVD magazines - if you want to watch DVD films - get a DVD player! I did and it's great.
Basically anyone who gives the Dreamcast 3 stars or lower simply has not played it properly or just does not know what really good quality games are. I own a PSone and I am fairly fond of it but very few of its games stand the test of time, whereas DC games do and will.
Every time I power my DC up whether on my own or with friends I know I am playing the best games available. It has a least a couple of top quality games in nearly every genre. Don't worry about production ceasing - there are still loads of great titles to come and the prices will drop soon after release.
Dreamcast is the best console I have ever bought and I hope you make the right decision - to experience the best graphics, environments, gameplay, innovation and FUN that videogames can provide.
