Well you are a bit too critical nex, I see your point but the game is quite old and still good fun and played buly lots with new content, its one of those if you have time you grind it or if not you pay. Thats how it goes this days
But it is not quite that simple. If R* had increased rewards for mission/heists/races et all, then the player base would have a better chance of accruing money in order to pay for the increasingly expensive DLC items. When I started (PC) the most expensive item was the adder at 1 million. Now 2 - 3 million is the norm after upgrades. Business ROI is many many hours before you make a profit. The game is geared up for grind or shark cards. I have 2750 hours online. I have only earned 280 odd million.
The game has been ruined by the seemingly unattainable without spending cash. Kainz called it. Freemium is now the model. I am surprised they have not spun off GTAO as a free game and added ******* coins to collect on the streets.
I am still playing as I have game mates and I really enjoy it. I am very lucky in that I have money and can basically buy what I please. That can not be said for new players. I also think this will be the last PC release unless consoles get cracked. Take2 have spent to much time and money going after PC modders to prevent cheating when they could just cut their losses and say, no more, concentrate on Xbone and PS. It is after all where the cash cow is.
On another note. I have finally completed the bunker firing range and I feel very smug.
