Yup..it would still count as a terrorist hunt mission.
Coming back to the topic ...
Well it's just Stupid with a big 'S' to compare Gears of War with Rainbow Six Vegas. Gears is a sci-fi third person shooter game while Rainbow Six Vegas is a realistic first person shooter.
None of the two games are too tough in single player mode. Vegas can be called a little bit tougher but overall both the game are playable.
Gameplay ... Vegas' gameplay is exciting as you have to plan according to snakecams and stuff and you have to be very very concentrated. GOW is more on the fun side but even then you have to take cover at times and be sensible.
Graphics ... Easily GOW is much better here. Vegas has average graphics and GOW has had the best graphics yet.
Story ... Story of Gears of War is definitely much better. Infact, Vegas doesn't have any story except for the fact that there are terrorists in Vegas which we have to clear. But that's pretty expected also since I don't know what story could they have with a style of game like Vegas.
Multiplayer ... Have to give Vegas an edge here. Simply because it has more variety in its multiplayer. Gears has an awesome multiplayer as well and that's why we love playing Gears of War online even if there is just one game mode. Vegas has plenty of game modes and it's really better online.
Overall ... Gears is slightly better than Vegas overall but it's sill close to decide. I personally liked Gears more but that may not be the case for everyone. I still believe that these two games have been just excellent in their own fields and we really can't compare two totally different types of games.
