Dreamcast worth picking up?

I never purchased a Dreamcast so I've had very little experience with its library of games. Would it be worth picking up a used Dreamcast to experience the games? Do they hold up over time? Or should I wait and see if they release the titles to Xbox Live or PSN?

I would say so, you can get a Dreamcast fairly cheap (The last I checked on Ebay in the UK it was £40 which is the price of a new game) and some of the games hold up really well. Some of them dont hold up just as well, as the Dreamcast Quick Looks would tell you, but theres enough really fun games to be worth it. Sadly though the online dosent really work anymore, even if you get the broadband adaptor (since I assume you dont have dial up) theres apparently only 3 games that work on it anymore and they are not really played.

Basically id say if you can get it cheap its easily worth it :)

EDIT: Oh I forgot that you can still play PSO online with a fair amount of players. If you get the broadband adaptor (or use the normal dial up if can) you can changed a couple of the settings and connect to a private server (which is essentially legal since when Sega Japan closed their server they gave them the data for it) which has a bunch of people playing and all the content supported on Dreamcast (and more if you download the free Blue Burst PC Client).

Hmm, well if I do get one what would be the essentials? Skies of Arcadia, Sonic 1&2, Power Stone 1&2, and Marvel Vs. Capcom are definitely on my mind.

Although some dreamcast games are going to be quite dear (like Ikaruga I think, though the XBL version might have brought it down) id suggest looking into Shenmue (since its a relativly unuiqe experience), Chu Chu Rocket (especially if you can get friends together and multiple gamepads), Rez, Jet Set Radio and Metropolis Street Racer (Read: Project Gotham Racing 0.5). Oh and Phantasy Star Online, though it was better at launch (more players online and the first of its kind on consoles really) its still a really fun game and worth experiencing since its referance so often especially since if you get a Broadband Adaptor you can still play it online for free :)

Most of the games we both brought up are the games that feature in Top 10's, sadly I cant think of any game outside it just now.

Are games like Grandia II and Skies of Arcadia better on the Dreamcast or PS2/Gamecube?
 
Also, how does the Dreamcast hold up? Are they pretty long lasting?

The Power Stone games and Street Fighter III: Third Strike (on PS2 but whatever).

no dude you don't need something to cast dreams for you.  Just go to sleep, and they will come.

Yes, go pick one up. 
 
There's also plenty of games on Amazon that are very cheap.
