Portal
Fallout 3 was pretty terrible. Hey lets introduce a mechanic that mutants are immune to radiation, but hey lets take it away again an hour later.
Isn't that basically what NFS:U did before it?
When did they take it away? It's possible I've just forgotten.
Playing deus ex for the first time really soaking up the atmosphere and being careful in all my choices.
Only to realise that nothing before the last 10 minutes of the game actually counted.
