2008 may end up being the year of the sequel. Just listen to this lineup of high-profile follow-ups: Super Smash Bros. Brawl, Grand Theft Auto IV, Ninja Gaiden 2, StarCraft 2, Fallout 3, Metal Gear Solid 4, Resident Evil 5, Mario Kart Wii, Guitar Hero 4, Resistance 2, Gears of War 2, and Call of Duty 5. Hopefully these games warrant their existence, and we're confident many will.<br> But what about new games, the ones that lead not just follow? Marketing types call them "original IPs;" we call them risk-takers. So in an effort to applaud their individuality, we profile the most promising ones for the rest of the year, based on first-impressions, breakout potential, and pedigree. A handful of titles are based on existing themes and ideas, but their creative spirit should not be overlooked.
