This game has been a huuuuuge dissapointment for me. I've been a fan of the series from day 1. Every entry in the franchise has brought it's own additions and gameplay tweaks, whle holding on to the unique stealth/action balance that made Splinter Cell special.
Conivction just doesn't feel like a Splinter Cell game. Every aspect of stealth gameplay that made the series special has been dumbed down or removed completely. The gameplay focuses entirely on your gun; Sam always has it equipped, and there is always a crosshair on screen. The gadgets are all redundant: flares, emp grenades, sticky cams, etc. all fill the same roll in gameplay. You throw a grenade to stun the enemies so you can get close. melee, then mark and exicute... or you get spotted by the enemies, so you throw a grenade to stun everyone, etc. Repeat about 500 times over and you have the entire game.
