Yes, that's true, the German version (at least the original CD release) comes on two CDs. They both have the same game data, but different audio tracks (so you'll have to change CDs when you enter certain cities or dungeons). You'll also get different tracks for the options, maps and stuff, depending what CD you're on.

I'm thinking about getting these games and I'm curious about sound fonts, which I am not familiar with. I gather that using them could actually improve the midi music in any game? Can anyone recommend some sound font tools, preferably free ones? Thanks!

Please share your playing experience with us if you finally decide to give it a try :).

One thing special about the RoA series is that they are more story based and not as combat centered as other rpgs which are mostly about killing randomly respawning monsters again and again to level up.

Thanks for your feedback!
You bet I will. I've decided to buy it (and I'll do it right now), but It will take a while for me to start playing because I want to finish Might and Magic I (I guess I'm already halfway through it).

I like your attitude, persistence, and patience concerning this type of game and the extra work involved (note taking and graph paper cartography) in completing it that appears to be extinct in modern iterations of the CRPG category.
I also just bought the games from GOG and am about to start RoA 1 in a few minutes. I played (and finished) this originally on my old Packard Bell 486 back in 1994, and had a blast doing so, but I must warn you that there is in the sequel (and maybe in part 1) a part in the game where if you don't follow the correct sequence of events, then you've no hope of ever reaching the end of the game, and you'll have no means of backtracking to correct the error. Other games in which this flaw manifested that immediately come to mind are Ultima IX, The Elder Scrolls: Daggerfall, and Might & Magic IX.
My advice is to spare yourself the needless frustration and make use of the free cluebooks that GoG makes available to you after you purchase these games so that you can avoid this pitfall with a bit of foreknowledge. The process of discovering for yourself the various elements of a well written game is indeed rewarding, but it's no fun losing hours and days of progress because of a shortcoming in a game's design.

Ok, thanks for the tip!

Yeah, the first two games are pretty good and I love the more tactically oriented isometric combat screen to the standard 1st person type of Bard's Tale series, M&M, etc. well at leats the ones with a party.
Can't say that it's better than M&M, but it IS definitely HARDER, and buggier or at least the first two were back in the day when I first played them.
Never got 3, as I somehow missed the Sir Tech compilation pack and don't recall 3 ever being sold separately in the US.
Now all they need is Legend of Faerghail, which was a pretty decent BT clone, and IIRC some people said that it also was losely based on DSA...
As to other old RPGs, Tunnels & Trolls is a pretty decent computer version of that system, but very unforgiving. Flying Buffalo is still selling that one directly last I checked a year or so ago, maybe they should just put it upon gog... (This one was written in Japan, EGA graphics(fairly late for EGA, but had this pseudo windowing system that worked pretty good. IIRC from I started to play again a few years ago it looked alot like the older Ultimas and would would switch to a combat window from travel showing all the chars in the party. I stopped playing when one of my chars got insta killed(TONS of ways that can happen in this game) and now way to resurrect them. Levelling a new guy up would just be a pain in the butt, and my quick look through the save file with a hex editor and some experimenting didn't reveal to me where the char status flag was at... (yes it is so annoying that I was going to CHEAT the char back to life...))
