I have not installed the new code, so my comments are based off the V1.23 description and my experience with the V 1.21 "old code".
I like the rulesets and challenges in a game. I want to see the wizard modes and features. Playing in tournaments is for points, playing at home is for the prizes and exploring what the game does.
The prizes to me are Danger Room, Dark Phoenix and Deadpool.
I had no problem with the Danger Room requirements before. I liked having to complete the Heroes to reach DR. I never asked for Heroes to stack nor even cared. They were not that hard to start and were not that hard to complete. Phoenix and Iceman were the harder ones, but something needs to be a challenge. (Even with the goofy ramp antics, you could do it)
Further, my strategy was to play as many Heroes ahead of Magneto anyway. Playing all Heroes raised the base jackpot to 1MIL. This also made defeating Magneto easier since all shots were available to decrease the health meter. If you went the easy route, lit locks and just hit the Rogue shot over and over (soft plunge lock, soft plunge lock etc), you'd only have one Hero and the points were almost worthless and she was the only one lit to decrease the meter. You had to plan your attack.
So the DR rule should have been left alone IMO.
My issue with the game was always the lack of integration in the Villains. Most people played for Danger Room since it was easier to reach. So if you played a Villain, you were encouraged to time it out. (Unless you had say Sentinels ready to stack with Magneto).
The Villain modes were polar opposites of the Heroes. Long as heck, and obnoxious to finish them all. No progression so you had to be dead accurate and fast. Not that it is a bad thing, but way harder than Heroes. Players figured this out and started wondering why even mess with this if I am trying for Danger Room. You did not want Villain lit and would curse if you hit the lit scoop. So, start Villain, trap ball for 60 seconds return to playing Heroes.
Right there is the problem with the game!
The player should never want to NOT do something and not have to wait 60 seconds to go back to what they want to do. The game should have a risk/reward. So if battling the Villains was easier depending on how many heroes you completed (akin to the Magneto rule) then there would be reason to play more Heroes AND a reason to battle the Villains-other than starting your 5th mode for extra ball.
I never really had an issue with starting Hellfire Club or Brotherhood. The rules are fine in the earlier code. The problem, again, is that there was no real reason to play either. Defeating all of the Villains is a massive task with 3 balls + 1 extra. Whenever I felt like exploring those multiball modes I would just play them. I typically just focused on Danger Room. Which goes back to fundamental issue.
The argument could be made that it is "integrated"; completing Heroes and Villains will get you to Deadpool. Players can figure out when a task is out of reach and Dark Phoenix and Deadpool are classic examples of holy crap that is a lot of work! A good game taunts you into keep trying for the goal. Come on you almost did it! Try again! When I just focused on Villains I never was close to all 7 done. I don't recall hear anyone even playing Dark Phoenix legit. I think the difficulty made players abandon the Villains and played for Danger Room.
So as far as stacking is concerned, there really needed to be a way to use the Heroes to advance through the Villains. Examples: use Weapon X with a Villain and defeat them easier with multiball. If a player completed more Heroes, it makes the health meter decrease faster. Each time Villain is started, a player would naturally have started more Heroes, maybe even completed some. The incentive and ability to defeat Villains is building naturally as the game goes on.
The X-Men game has tons of potential. I am hopeful it will eventually come around, but I am a bit disappointed (not angry) with the integration of rules so far. And for the record, there are plenty of shots/combos-there should be some reward for that, but that is an aside to the "prizes".
Thanks for reading
