So....after reading some Steam reviews...
I think I'm going to hold off buying it.
It's made by the guys who did Wizard Wars and their finger prints are all over this one, carrying over design choices from there into the new game. I didn't play WW, but apparently...
-The movement scheme (moba-style left click versus click and hold to move) is from WW, and results in floaty, imprecise character movement.
-Fewer elemental combinations. No more Steam/Ice, no more Lightning Beams, several other missing combos. I.e. the simplified system they brought from WW.
-Can't aim many spells via the mouse like you did in Magicka 1. (Teleport is now just random rather than being directed.) Probably because consoles don't have a mouse pointer.
-Harder enemies and more of them. They hit harder, have more life, your spells are generally shorter range, and everything but fire seems to have been neutered. People describe doing a shit load of kiting just to stay alive because they can't get the time to either a) cast magicks or b) cast the ones that actually kill things. Bosses designed for team fights are making solo very difficult. Swarms from all sides of the screen.
-Many spells seems weaker across the board. Magicka doesn't do elemental immunities anymore, only resistances, with the exception of 1 spell combo. As mentioned, ranges are shorter. AoEs aren't as large based on how many elements you throw into it. Rocks apparently have been nerfed to the point they don't feel worth it, as fully charged they do less damage overall than the first few wind up seconds of a straight fire spell. Fire seems to be both the easiest to use and the most damaging. Many people say spell balance feels off by miles. They seem to have done their utmost to prevent spamming spells in most cases.
-There's a quick cast button to just cast "memorized" spell combinations. The trade off using them vs. normal casting is it introduces a cooldown.
-Unnecessary, stupid tweaks. Like frozen guys losing the ability to be shattered by rocks, but now they reflect beams? I don't even....oh right. Wizard Wars.
-Requires a Paradox account to play multiplayer.
-No offline play.
-And the cardinal sin: No rebindable keys. That alone tells me this is a PoS port.
Plenty of red flags for me. It seems like after going through the PvP ringer of Wizard Wars, Magicka is a more balanced, streamlined and consolized game than before. Which to some might make it more boring. It seems like a classic case of someone picking up another dev's game through a publisher, and changing things with an eye toward mass market appeal. There's additions, sure. You can customize your wizard at the start of each level, find new robes and gear to use. There's artifacts or something that tweak gameplay if you choose to use them. But that all seems like window dressing for the fact that the core gameplay has been fooled with. It's less about super broken and OP spell combinations, and more about team fights and more enemies.
A phrase I'm seeing bandied about a lot is: "Think Dark Souls 1 vs. Dark Souls 2." When you screw with the formula that many people enjoyed, you're bound to lose some of them. When Wizard Wars was an offshoot I didn't really care, but, now that it's come to own its namesake, I do kinda care.
I'm still hovering between buy and not buy, but if i'm honest at this point my motivation to buy is to confirm or refute the negatives I'm reading, rather than from any real desire to play.
