They were not terrible. The 3d mortal Kombats are what got me onto the fighting game scene. The worst one was vs DCU and thats because of the T rating. Armageddon was also a little lacking because of the fatality system. However they were great games and recieved great reviews.
you know what didn't recieve great reviews, 3d sonic games.
Then you're missing out. The original MK trilogy were far superior than the modern crop (except MK9, which actually surprised me with how good it is).
By the way, game reviews don't matter. The opinions that matter is the mass market who actually play the games on a regular basis, not game critics because most of them can't figure out how to even use a controller. They are also quite biased.
In regards to the 3D Sonics, they are not bad games, but they don't even come close to the quality of the original 2D games (especially Sonic CD, the best out of all of them in my opinion). I've always been a Sonic fan, so the direction that Sega started taking with Sonic after Sonic & Knuckles was quite disheartening for someone who has always liked Sonic. The best ones for the 3D Sonics is Sonic Heroes, Sonic Colors, and Sonic Unleashed (if you don't count the werehog stages, ugh). Sonic 4 was okay, but mediocre at best. I've been hearing great things about Sonic Generations, so I'm going to get a glimpse of my brother's copy on Friday to see how it plays.
To everyone here, DLC is the norm these days. Deal with it. Pretty soon, hard copies of games will be obsolete anyway due to how cheap it is to make a game without a physical copy. If you don't like it, too bad. Don't buy it. You're in the minority anyway, so a business could care less if you're feelings are hurt.
