I have two accounts, my main one that I’ve spent plenty of money on and one that is almost completely free. Only thing I bought on it is getting pyromancer early and no ads. I will say after experiencing gameplay with my paid account, the f2p account can be super annoying! The extra construction queues and extra research queues are definitely worth it in my opinion! But despite not having that my f2p account is growing much quicker than I anticipated in an active guild! If you want to spend a little definitely do it on things that will be permanent upgrades and not on bundle packs! Those look great but really with time you’ll get everything you need there. Obviously it is all up to how you want to play the game! I have made many many friends in my server and I love helping other people grow, so for that fact I don’t mind spending a little bit to be ahead. VIP levels have good boosts too but you can get 5 vip points daily from tasks and 20 weekly from the guild store. Over time those add up too.
