Regarding spending yr hard earned CASH!!!
For over a year I refused to spend cash on this game but then accounting for the amount of time and effort I put into this game and also reaching level 9 with only 3 droids was a massive headache when wanting to upgrade but have 2 Deka's that need a droid each for repairs!!!
I thought to myself the amount of times I go out on a weekend and burn money on drinks for myself and others which easily amounts to over £100 each weekend I thought maybe spend less than 25% of that on some crystals which has kept my arse in on weekends and have the benefit of a couple more droids and has helped massively on upgrading my base a lot quicker... So I real terms I'm actually saving money!!! Well that's my experience anyway... All the best jj
