It's the case for all other "free games"... I don't play Candy Crush (for instance) but this is the best example you could give together with Top11. I play MoviePop and SongPop, I don't spend money there, but these games are built in a way that it's less addictive. But still, you can buy things with real money there as well. And all the games I've mentioned here are categorized as a free game because in the end, YOU decide to invest real money (although "invest" is not the right word as this means you will gain something with it, which is not the case). They don't force you to do it.
To come back to my initial post, I don't think it was wise from me to buy these 37 tokens. I just wanted to win. So, now, winning is no longer a priority for me. I don't buy tokens any longer, I just want to see my stadium fully built. Less challenging objective, but saner :-) and good for people who like spending money in order to get virtual trophies... my only problem is that they brag about it but here again, I've stopped reading what they write![]()
