Quite an old topic, but I could go on about both for ages so I'll try to keep it short.

Killer 7 completely floored me. At the time, I had never run into a game so strange, so gloriously violent, so disturbing, yet so deep at the same time (yes, I played the MGS series before playing Killer 7). The psychological implications of the game kept me thinking for literally months and I have to admit every now and then I think of Killer 7 and think, "what did *insert scene/character* really represent? Why? How did it effect the game?" Gameplay wasn't amazing, but the stories of the Killer 7 (or 8 or 9 or 10 depending on your views) was just so mind boggling that it remained one of my favorite GC games of all time if not the entire gen.

No More Heroes on the other hand, is like Suda 51's way of taking a complete s*** on that mantra and going for a stylistic bloodbath with characters that can never be forgotten. What it lacks in pscyhological discussion, it makes up in sheer awesomeness. Sure, the gameplay was a bit bland, but everything from Travis's quips to the characters' names completely made up for it to make it my favorite Wii game after Super Mario Galaxy.

So in the end, it'll be Killer 7 because I'm in a psychological mood. I'm sure that my opinion will change again though after enough time has passed.

Wii Sports-If we're talking about mature as in age, just about every casual falls for this one.

Civilization 4-If we're talking about mental maturity, this one will definitely impress them. Unless they're the sort of a mature person that doesn't believe in "altering the very fabric of human history for foolish trifles such as gaming." :P

Half-Life 1 or Half-Life 2+episodes-Depends, 1st impressions may not be that great (I know I wasn't that impressed with HL1 when I saw it being played for only 10 minutes, took at least an hour to really get into it) but if they "get" the story and the mechanics, it's definitely going to leave a good impression on "mature" people.

Never happened, but their reviews have subconciously effected how I view a game when I play it. When I played FE:Radiant Dawn, I absolutely loved it since it was exactly like Path of Radiance (with the exception of butchering support scenes), but then I read the review which pointed out all these flaws and when I started playing again, I couldn't help but notice them now that GS pointed them out. I still enjoyed the game, but those little flaws GS talked about kept coming up in my head over and over again.

If people will elect a man as presedent just because they saw his advertisement in a video game then we deserve a horrible next 4 years.Timstuff

Agreed, but we Americans are naturally shallow and easily impressed by subliminal advertizing. If the candidates attempted to advertize themselves through honesty and good faith in the American people, less than 10% of people would be voting.

Best

Persona 4-but since someone already posted the cover, I'll just post the pic that caught my attention and got me interested in the game. I loved Persona 3 but didn't even know the P4 existed until I saw the artwork. :P

Worst

Left For Dead-I was really disappointed when I saw the cover. It's funny really, Valve makes AMAZING games that can easily trump modern competitors in terms of gameplay, immersiveness, and wit, but recently, they utterly fail when it comes to making interesting boxarts.

Why are we still arguing about this? Aren't there more recent games to be scrutinizing over instead of NMH? Was it really that controversial? But whatever, I say yes. NMH was over the top awesome in just about every way. It was like the kind of game I wish existed when I was a little kid. Over the top satirical violence, insane character designs, and a story that made me go WTF at least 10 times. Yes, the graphics were horrendous, but I think the awesome artstyle and sense of humor more than made up for it.
