Interesting someone upped this thread. I've downloaded every single Dreamcast title ever released including JP ones and I'm currently exploring its game library. So far, to be brutally honest, I haven't found anything that interesting yet, but I've only just begun, we'll see how it goes. I've played about 8 hours of Evolution 2 and was unimpressed with it. Wrote a review of my experience here

I've also played EGG some time ago and that game is really good. Unfortunately several threads on the archive are broken and you can't access my original post anymore but I did save my review of that one in an anon blog I used to save my game reviews, you can read it here;
https://gameboy2017.wordpress.com/2019/08/08/206/. Definitely a game I recommend if you want to play some dreamcast stuff.
I've also played both Crazy Taxi titles for this console and they're really fun. I didn't write reviews on those because they're fairly popular titles even today and I don't think I have much to say about it. It's a very arcadey game and it works best if you play 30 min at a time, otherwise it might get a little bit repetitive. It's a very fun game though with a lot of replayability.
I've played a few hours of Radirgy, an interesting looking shmup with bullet hell bosses. I did enjoy it for its visuals and odd story (for a shmup anyways) but overall it's a shmup experience you can get with a lot of other games, from the Dreamcast itself and other consoles and PC. Nothing really stands out other than how it looks. Visually it's very unique and worth a shot because of that. I don't think people who really like and play lots of shmups will be impressed with it though. Its gameplay is really standard.
A game that did stand out to me is Rez, but I've only played a little of it at the time of this writing. It's a weird rail shooter where you can shoot enemies and they make a beat you can synchronize with the music. It felt a little gimmicky but I can't remember a game quite like it, especially from that era. I guess that makes it a unique gaming experience. I'll try to complete it sometime soon, I checked a video on it and it's a fairly short game.
Finally I’ve played a little bit of Bangai-O, a game I was looking for since I’m an admirer of many Treasure titles, specially the ones they did for the Sega Genesis. It’s a no-nonsense 'shoot everything you see on the screen' and it works really well. You’re this tiny mecha bringing down fire across every surface of the map. I think it deserves a full review, I’ll play more of it first. Btw if you’re emulating Bangai-O on the Dreamcast you’ll need the Dreamcast BIOS files, dc_boot.bin and dc_flash.bin otherwise it will lag a lot. With the BIOS in place it will run perfectly. You can find it on the internet archive.
And that’s that for now. I’ve watched a yt video quickly showcasing every single DC title and picked up about 50 that appealing to me for one reason or the other, I’ll be trying those first. We’ll see how it goes.
