I hope the Gamek­ings put some nice stuff to­geth­er about the slight­est de­tails. The is­sue I have with pro­fes­sion­al pub­li­ca­tions sur­round­ing games is that you know it's just some guys bat­tling them­selves through a steady stream of new games and they hard­ly have time to re­al­ly get into most of them. So the re­views are usu­al­ly about the bare min­i­mum and by the time play­ers have had enough time to find bugs or the real depth of a game it's no longer in­ter­est­ing to men­tion any­thing about the game, while some games have enough con­tent and depth to re­vis­it them for a se­ri­ous­ly deep re­view long af­ter the game is con­sid­ered new.

So what did I no­tice in GTA IV? (Be­sides a ton of in­cred­i­ble de­tails that are pret­ty ob­vi­ous)

• The in-game screen of the phone your char­ac­ter is hold­ing is the same as on the phone used as the game in­ter­face.
• With your con­troller you don't con­trol the ra­dio, but you con­trol your char­ac­ter who then con­trols the ra­dio. The move­ment of chang­ing the ra­dio sta­tion in a car is mo­tion cap­tured, and while in a taxi the char­ac­ter asks the dri­ver to change the ra­dio sta­tion in­stead.
