No I've never played the PC versions. I've seen videos though.
I can't see how the gameplay will be hugely different. Surely it's the same game underneath? And with no bags blowing around and other 'pointless shite' it will feel really bare bones and basic to look at as it appears to in that video and how people said a while back it looked.
I did like BF3 at first. But then the community just became crap spamming laser sights to blind you and relying on all the cheap guns and bunny hopping and a real lack of vehicles for the defending sides. Like you'd get 1 anti air vehicle but the enemy would have 2 choppers. It was fun attacking but terrible defending. Then they went and made it even worse by making mines vanish on death and removing the servers and then the custom servers are just riddled with idiots who kick you as soon as you kill the host.
BF isn't really a game that I would ever say I enjoyed playing though. There's a constant feeling of helplessness in there. Either from spawning miles away from the action and being killed by enemy snipers on a hill nearby or finding your team stuck in a bottle neck where the game boils down to spam grenades until the timer runs out.
It's like for every game you play and things go well and the teams are nicely balanced... you'll have to play for 3 hours in shite games where the enemy just walk over you or your team walk over them and you never see the action.
Oh I'll get in a tank and take out that other tank over there... oh wait someone's already took it and has parked it at our spawn to take shots at men in the distance. Oh well I'll grab the chopper and transport a bunch of us to... no wait... someone's taken that, on their own, flown to the top of a hill.. and is sniping at dots in the distance with a K/D rate of 1 kill and 12 deaths.
I miss Bad Company
I don't think Watchdogs is going to be much different on next gen. it will look cleaner... but they've not shown anything there that isn't possible on current that actually affects the gameplay.
Assassins Creed... I've had my eye on that and they seem to have put quite a lot in on next gen that should mean it does feel a lot better than current. From how the oceans work and look to the lighting of the world and volumetric fog, the way raindrops reflect light, wind effects the 3D foliage, the draw distances when out at sea. From all the next gen games coming I think AC4 is the only one that has jumped out to me as looking like a large step up from the PS3/360 version that will come.
