I actually remember when I heard X-Men was coming out and hearing it would only be on the Genesis and being so grumpy about it. I was 10 and I was lucky to have both systems at that time. My cousin gave me his Genesis and all his games for nothing (and I still don't know why) but I still liked my SNES way better. But.. but.. but.. X-MEN!!!
X-Men are my favorite team too, so much so that if Marvel broke the team and all it's books (and I mean ALL -there were so many of them in the 90s) off of their company in the 90s and made it it's own entity, I likely wouldn't have gone back to Marvel for anything other then Spider-Man; That's how much in love with them I was.
When the game came out I remember hearing my parents were going shopping across town at Woolworth (it was one of the last still open at the time) and somehow I knew the store was carrying the game, in a day where it was VERY hit or miss for certain games to be carried by retailers (I remember how impossible it was to find Mario 3 in our town). I had the money left over from a holiday and decided (like there was ever a choice in my 10 year old brain) to go with them to get it.
Man, that box art was something else, nothing like you'd see in the comics of that time; it was about 10 clicks above the best cover art at the time. I'd be surprised if that box art alone didn't sell a bunch of copies of this game. And I still have the packed in poster for the game somewhere -I always wanted to put it up, but I was a weird kid who knew there was some sort of value in these things, so I wanted to frame it, and we never got a frame for it.
But the game itself.. Heaven and Hell all rolled into one. For one thing, I thought it was a beautiful game at the time --but that was at the time, we didn't really have much better at that point, and Genesis graphics were always slightly above most of what games for the Nintendo were. Later the SNES would see X-Men: Mutant Apocalypse, which will probably be my 3rd or 4th most played game for that system after Earthbound, Super Mario RPG and swapping places Power Rangers (don't ask me why Power Rangers -it was a pretty great beat'em up at the time), and I felt like that game ended up being the nicest looking X-Men of that period. But I didn't see a problem with the choice of X-Men we were given on the Genesis version, and I loved the team members who would pop in to help. The environments were interesting considering I knew where we were put, and would geek out to see The Savage Land and all that -it didn't really matter how they looked at the time, it was a privilege to be there regardless.
The gameplay though.. Holy hell was that the worst.. It was a Genesis game, so even then I knew from playing stuff like Altered Beast or Shinobi that there was a certain expectation of skill when a game came out for a Sega system. So it was easy to assume that the game would be hard. But this was HARD. Like the review states, every player character has a 1 inch punch, even Gambit who actually had a weapon in the form of his staff, while pretty much every enemy has unlimited ranged capabilities. It's just painful when all you can do with a staff is slap dudes in the shins.
The other thing, like the review states, is the extremely limited use of their powers. I get why they did this, they figured if there was unlimited use of things like Kinetically charged cards, optic beams or healing factors would make you godly in a game that wants to be as close to an arcade game as it could get --which, because there was no saved states, meant needing to restart the game from scratch if you happened to die.
Those two factors meant I never got very far, and meant that when I heard Clone Wars was coming out I made the mistake (a very very rare mistake for me -I was a completionist even then, even if I didn't enjoy the prior game)to decide to pass on the game based on the experience I had with the first (and, frankly, the box art wasn't as nice... WE DIDN'T HAVE THE INTERNET YET, OKAY!? lol). Hearing it was a much better game hurts me in the heart parts, even today.
