    The max resolution is like 1280x800 or something, and my FPS was so bad that the rendered cinematics were lagging and had choppy audio.

    Latest update broke mods and fixes for stuff like stuttering, AA, crashes and modern monitor resolutions.

A further 10 reviews call the game buggy or broken without saying how, which is why they are counted separately rather than assigned to a theme. Counted by keyword across review text, so a review discussing two problems is counted under both. Read the reviews yourself.
