Don't worry. We are reasonable people, not the super sensitive forum polis type. Highlight what you need

For CE I can only recommend go for those that you really like. Else the expenses is going to catch up with you really fast. Personally I only buy a game once every 3 months. (my average per game lifespan) RM180/3 = RM60 per months ++. Something most ppl can live with. Some advise for sharing:

Single player games: Short lifespan and re-playability. Ppl finish will tend to try sell it off. Don't rush for day 1 gameplay, its the same if you play it 30-60 days later. Promo will hit the block soon. Like now I can buy fallout 4 at lower price compare to 239 during launch. Its still single player mode anyway.

Multiplayer games: Due to the multiplayer factor, you probably will have to follow the mass crowd aka week 1 purchase. This one you will have to invest to buy at premium price.

Selling off a good quality CE to fund game is quite a waste imho. (if main living necessity then different) Esp after u spend so many effort to bring it in in good condition, and it is a piece that you really like. Some CE also once out of production the price sky rocket too. Personally I sold off those I don't like that much and only kept a few.
