pc's have nebulous permutations of set-ups, hardware and software, so problems are quite understandable which is one of the reasons i wait at least a month or more before buying a new game after its initial release... i can also vaguely accept the presumably temporary lack of promised dlc content, as this varies between purchase outlets so there's a modicum of outside-the-game element...
but the xbox and ps are essentially 'sealed units'... so where's the problem ? an ex computer programmer/anolyst's only suggestion is that it's the testing...
one almost expects the odd glitch like getting stuck in a corner or behind a door or something... these things shouldn't happen if a program has been properly tested, but they do happen, because we are all human and when a tester says 'the area's secure' then he's showing that he's only human by getting it wrong... however, although the number and severity of glitches, freezes and downright errors on this standardised platform may not be the worst i've seen or heard about, for a game of this standing and with its guaranteed uptake/income, i feel that it is unacceptable that the game was released in its present state...
i know nothing about game testing, so maybe i'm missing something here but in my eyes, testing is testing... this fantastic game was programmed beautifully but not tested properly...
