Everyone seems to support R* like they're godly
Anyway, I agree. I haven't gotten massive amounts of money, but I do have around $60 million, and don't see much point in getting more.
Properties are nice and all but they take a long time to return your money and start actually earning. The only real advantages are perks like free cab rides
Guns can be maxed out and every gun bought for around $50,000 total for a good stack of ammo with them.
Cars are a good idea, but somewhat pointless. I bought the Adder and that's the only car I see any point in buying, since most sports cars have the same top speed and maxed out acceleration. Upgrades are a good part that I like but frankly, not really worth it. You can only really upgrade the acceleration and braking (slightly). Not to mention that cars with special uses during missions lose that use in free roam. Like the JB 700 that has un-usable guns and jacks.
Planes/Heli's are semi expensive, but most you can just steal anyway. I stole the fighter jet and plan on getting the combat buzzard soon. They would have more purpose if you could customize them (which I really hoped we could do)
I wish they would have had a way to buy houses and fortify them or upgrade them. Or a way to pay for armed guards/gang members to help you or guard your safehouse. Or added more garages to buy to store cars you can buy
and this is semi off topic, but the stocks seem extremely unbalanced to me. The graphs have no actual relation to the stock, and as soon as you buy a share the stocks seem to go stagnant. I sat on a stock that I bought at its all time low for an in-game week and it hadn't gone up. It actually went down.
But anyway, I agree. There really isn't much to spend money on. Before you try crucify me for saying it isn't "good enough", I'm saying it's better than GTA IV, but not a complete fix.
