So, on twitch yesterday, Game Informer did a live stream, where two of the guys were playing Madden. I'm at work right now, so can't post a link, but if you Google twitch game informer ps4 live stream, I'm sure you'll find it. I think it was at the 1:50:00 mark of the video that they started playing Madden.
Now, the video was not impressive. In fact, it was downright depressing. I think it's safe to say that after seeing that, it's pretty obvious why EA Sports has avoided showing normal gameplay for the game. It just doesn't look very next-gen at all. There just isn't any way around it.
One caveat I will speak to however, is that the guys decided to turn on the "rain" weather effect, and it's possible that the game just looks kinda crappy without the sunshine on the field. I know that might sound a bit ridiculous, but if you watch the stream, you'll see what I mean. I know this game can look better than that, and I actually think the lack of sunshine could be a big part of it. So, I'm still going to wait to see some reviews, but I would definitely curb your enthusiasm before buying this game. You need to have very low expectations, or you're probably going to come away extremely disappointed.
It's really quite sad that this is the scenario, because some of the more recent videos actually had me excited, and then I saw what I saw last night, and i'm like.... "damn."
