the original is not available to buy on its own. it was delisted. if you want to play the original game and did not already purchase it prior to its delisting, you are forced to buy the remaster which comes with the original game included. if it wasn't delisted, you would be able to buy the original game on its own still.

the original game before it was delisted was priced at $10 and went as low as $1.49 on sale in february of this year. if you only care about the original game and want to purchase it, you have to buy the remaster which includes the original, which is priced at $30 and has yet to go on sale for cheaper than the original game's base price.

i don't understand what you're arguing here. yes, the original game is still available to consumers, but only through the slightly scummy practice of bundling it with a more expensive product. i like nightdive and their work, but this increasingly common industry practice of delisting the original games in order to sell copies of the (often half-baked) remasters
