First of all I would like to say that I'm in a grey zone if I like this game or not.
The Drafts/Tournaments are super fun while the regular vs-mode is "meh", and if you plan to play a lot of drafts this game will probably require money.
I would also like to point out some of the reviews I've seen here. Some reviews claim this game is pay to win. It is not. If you think about it any TCG is "pay to win" at the start. You should never start playing a TCG with the belief that you're going to be on par with players that have played several weeks more than you, it doesn't work that way. This is the nature of any TCG. You can't believe that you will be able to beat any player with more experience and invested time than you in any TCG with your starter pack. Be it an IRL TCG or a computer TCG.
Let's compare SolForge to some other TCG's like Hearthstone and Scrolls. In all these three games you can pay real money for booster packs. Does that make them pay to win? Well, maybe. But let's compare them to some IRL TCG's... NO WAY! You pay MONEY for CARDS that may or may not be better than mine!?!?!++ PAY TO WIN!!! PAY TO WIN!!!
You see how silly this becomes? Yes, a core element in a TCG is that it IS pay to win. But in all the TCG's I mentioned above there is the option to "grind" for in-game gold that you can buy cards for, and doing casual drafts in SolForge will surely get you started!
Another complain I've seen is that some reviews claim RNG is a major part of SolForge. I'm baffled.
In SolForge you play with a deck with 30 cards. You are allowed to have 3 copies of a single card. This means that you could make a deck of just 10 separate cards (such constistency!). In SolForge you discard your hand (5 cards) and draw a new hand every turn (in which you may play 2 of them). This means that you in theory can go through one copy of each of your cards in just two turns, and there are a lot of cards with good synergy!
Compare this to Hearthstone. You can have 2 copies of a single card and a maximum of 30 cards. This means 15 different cards in your deck, minimum! You can also only draw one card every turn (with some exceptions). This means that you would need atleast 15 turns to go through each separate card in your deck.
It does not take a math genius to tell the difference between 2 and 15...
Except from this the whole "So much RNG"-point is strange since RNG is a core element in any TCG. Some TCGs have more and others less.
TLDR; Do not listen to the ♥♥♥♥♥♥♥♥ reviews, try the game because you may or may not like it.
