Adding to all buttlover said, I heard from new players on other forums that you also get 21 free SCs in the span of one week. 3 free login SCs with your regular login bonuses per day afaik. And if you fail or give up a mission, half of the charisma and stamina will be refunded to you so it is as buttlover said, DMM is more forgiving with all the new updates.

I remember when I first started playing at DMM, it was overwhelming at first with the continuous chain of events, but I slowly adapted to them and doing alright there now. The new UI will also take some adapting too, but you'll get used to it in no time.
