Is A.R.E.S. worth buying for trading cards ?

Are you asking if the game is any good, or do you want someone to calculate whether it's probable you'll make a profit on the exercise?

I found it completely dull. So only worth it if you can find it very cheap and don't have a job that pays well.

It's worth it if you liked megaman X, otherwise no.

3 cards at a current value of about .40$ -15% is about .90$ + a rare chance at a foil. Anyways I think this game is fun enough to justify 1.60$ purchase. Even without the cards it's a fun enough to be worth 2.50$

or should i buy magicka instead ?

You will only make like $1 USD off it, with the cards. The game costs $2.49 or you can get the complete edition for $2.99. It isn't an awful deal, but we are mostly past the cards pay for the game stage. If you find a foil, that might be different, but they are also dropping in price. I look at it more like the cards provide a discount that might not be attainable elsewhere, unless it ends up in a future bundle or you get it from a past one. If you want it, the deal isn't bad, with the cards. It is this way with a few games. I have done this and also, in the past, got free games as a result of buying them for the cards. It isn't a bad approach, if you want the games.

If you're going to buy a game for cards, go for Magicka because you'll at least have fun playing it.
That said, I don't think you should buy a game 'for the cards."

I bought it and already regret it x_x

Bad game, incredibly generic and you can max out your weapons by farming the first room... Really poorly thought out mechanics and half don't even work/matter (changing suits).

Ok guys i think im buying Magicka. Thanks for all the information!

Nothing special, kinda enjoyable if you like the genre, but short. Best thing: the soundtrack. If you got it from a bundle it's okay, you can avoid it otherwise.
