This is an online gameplay review only.
People have been saying that you can't compare Black Ops to MW2 because they are from different developers, but I'm afraid that's all you can do. IW are the benchmark developers with Cod 4 and MW2 being the best FPS games around.
Black Ops in my opinion is an OKAY game, not life changing just pretty average. The whole online gamepley is slow in comparison to not just MW2, but also Battlefield Bad Company and MOH. The graphics have taken a serious step back by at least 6-7 years, everything is just so cartoon like on BO and patchy. The weapons are generally pretty poor with the exception of a couple, the grenades and other explosives are pointless as they have less power than a flying potato. The perks and killstreaks are worse than MW2 in which is an older game, surely they should have improved on them? The customisation is designed for kids, but being an adult rated game has no real place except for the less social people out there that spend ALOT of time on there own. The money system was interesting for all of about 2 minutes until you start to wonder why it is there?
The plus points are: Maps are pretty well thought out as always with Treyarch.... That's all I can think of for now!? I'm not going to be childish and give it 1 star because a 1 star game is unplayable but as an average game it gets an honest 3 stars. This will be my last Treyarch purchase as I thought WAW was also an average game. Hope this helps some people that may still be undecided about buying this game.
