Thief is going pretty cheap on most systems now so I bought it.
It's shit.
The game represents everything wrong with modern generic games. Terrible level design filled with scripted occurances, shoddy AI and incredibly boring gameplay. The areas are incredibly small and there is only a few ways to complete the levels. Everything seems conveniently placed such as windows, doors and cover. The NPC guards are awful; they are either blind or just spot you randomly. Whittling through the game just feels so uninspiring and tedious. Do not buy this even for a fiver.
