We also pay for PoGo. But, clearly it is for our convenience. We buy items bag upgrade so that we can carry more balls, etc. Pokemon bag upgrade so that we could carry more Pokemon of our choice. Incubators for hatching eggs, etc.
However, in PoGo, there is no cost for you to level up your mons. At least not in monetary terms. The cost is just stardust and candies which can be gained through cathing other Pokemons and the same mon. So very easy. Costless in real money terms.
JWA you need the mon’s DNA which is a pain in the ass. And to level up your mons you need coins. At lower levels this is not something that of a concern. But when your mon reaches L15 and above the costs are just insane. To power up a VRaptor from L20 to L21 you need 50k coins for just one level up! How many days do you need to collect that much coins?
Besides, PoGo gives us the opportunity to own all Legendary mons - painless and costless. JWA…? You have to pay through your nose.
I am a L40 player in PoGo. Played the game everyday. Reach L40 in a year’s time. My attack and defence team are all fully powered up. I have all the Legendaries. Most recent I was introduced to JWA. Took up the game and now is at L10. But I believe that I will be here at L10 for much longer than I have initially thought - since the only way for you to level up is by levelling up your mons which in turn is costly.
I still don’t have any Legendaries. No Uniques. Obviously if you want one, then, you will have to pay tons of money since it is the only way for you to obtain one - there are just few DNAs per incubator. So, you need to buy loads of them.
The amount of darts are also limited to 140. And seriously I don’t understand why 140. Unlike PoGo, I have more than a thousand balls of different colours which are used to capture the mons.
The only good thing that I could say about JWA is the number of supply boxes available. While it is easier for you to replenish your darts, it does not really matter when the amount of darts you can carry is limited to firing 10 mons only.
I will continue playing JWA ocassionally when I have the pleasure of someone driving the car for me and when there’s an event going on. It is very difficult to be competitive in JWA without spending tons of money which defeats the objective of making the game fun for everyone.
