- They Changed It, Now It Sucks!: The engine changes made in Rune Classic has driven some players to hunt down the older versions of the game. Despite featuring enemies from the PlayStation 2 version, and the cut and removed levels are negligible as a mod can restore them to their original forms, Rune Classic forces players to use an outdated Direct3D renderer and does not support third-party ones such as the DirectX 10 and OpenGL renderers. The Direct3D renderer used by Rune Classic lacks many of the advanced features the other renderers offers such as anti-aliasing and anisotropic filtering, and does not function properly on certain Windows operating systems. GOG.com adopters can download Rune Gold with the purchase of Rune Classic, but Steam users don't get this luxury.
- Demonic Spiders: The Sarks in late stages of game, which are basically the zombies you fought back in Hel except these monsters on steroids and even more pissed off than before. They tower your character, attack in groups, take a legendary amount of punishment, and some of them carry weapons that are bigger than your body, especially on Hard where they hit even harder and take less damage from your attacks. The amount of pain they can dish out can range from brutal at best to one-hit kill at worst if they manage to decapitate you. If you didn't have your Rune Power meter charged to use your weapons' powers before fighting a group of Sarks, consider yourself boned.
YMMV / Rune
