Sequiro: Ugh, not quite the easiest question to answer. Though i guess your own answer would be what would you care more about the sound or the graphics?
If I were forced to choose, I'm not a fan of Sony myself but if you are planning on being with Sony for awhile even beyond to the PS4 and such. I may suggest going with the Playstation version.
Now the resolution of the game will be far lower, as its just emulating the PSOne title. The PC version can look very crisp and clear because you can spike the resolution way up.
However the PC version is devoid of a lot of soundtrack (dynamic music) that changes and plays based on whats going on. The PC version just loops the same small tracks over and over. So you are getting a much much more rich sound experience on the PSN version.
Ouch seriously! Music is quite important for me. While the high resolution made the game look nice in a way that no Playstation game could, I find it is much more important to hear the soundtrack as it was originally supposed to be. Dynamic soundtracks are cool, and I also fear that a dynamic soundtrack converted into a simple loop a single track soundtrack, probably was done by someone that didn't care very much.
Since I'm not going to buy a Playstation any time in the foreseeable future I just bought the GOG versions of LOC: SR and LOC: SR2 and will later take, ahem justice (self-entitlement) into my own hands and play the original Playstation version of LOC: SR on my computer.
Do you know if Legacy of Cain: Soul Reaver 2 was converted to the PC in the same shoddy way? The graphics looked so nice for that one, it would be a shame to not be able to use the high resolution available in the PC version. Well at least the PlayStation 2 has a higher resolution than the PS1.
This sub-par way of treating the soundtrack of the PC conversion s reminds of the conversion of Rayman Forever. They ran out of space on the CD for that one (why not make it a two CD release then?) and cut out a lot of the soundtrack. Also, instead of having a unique tune for each level of the world, the PC version just loops all the themes for that world regardless of which level you are on.
Thanks to both of you, and to GOG for releasing these games.
