Admittedly, it's pretty bad, but I actually finished Sword of the Berserk: Guts' Rage for Dreamcast last night. In my opinion it hasn't really aged well, but it's a really interesting stand-alone, (non-canon) story-driven hack-and-slash game that I'm sure only fans of Berserk would really appreciate.
According to Wiki, "It takes place anywhere between volumes 22 and volume 23 of the Berserk manga; right after Guts and Puck depart for Elfhelm with Casca, but before Farnese, Serpico and Isidro catch up with them."
Anyway, my only real complaint is the lack of motion-acting, and the strange sort of one-sidedness in Guts' playability; he's a heavy guy, as you might imagine, and his warm-ups to strikes and defending don't stand up well against his decidedly quick foes, most times. Unless they're huge bruisers, in which case they fling him into walls regardless.
Also Michael Bell, do I love you, or do I love you not?
