Half-Life 2 Never got into it...but bought it for the mods, which ironically I never ended up playing anyhow.

The Witcher: Enhanced Edition Dunno, just something that put me off.

Medieval 2: Total War I hated how generic the armies were (after Rome, but also I felt MTW1 had better unit lineup) and most of all the lack of immersion/believeability. If I had good relations with another faction it did not matter, they would attack you anyhow even if they had 3-4 other enemies. Think I played more Broken Crescent than M2TW vanilla.

Empire: Total War Spent 10-15 hours on the campaigns total. And that was before the patches.

Crysis: Shiny graphics, good enough UI, but just wasn't interesting.
