Further, don't forget the law of subjective valuation. The fact that the FGC respect it now, the fact that it has such large tournaments and such a large playerbase after nearly 15 years, and the mere fact it has such mechanical depth, all lends to the 'one of the greatest games ever' statement. I didn't say best ever, just one of the greatest. I, for example, love Third Strike, and see it as a peer among the greats such as Brood War, Counter Strike Source, just like Melee. I understand if you don't think its pedestal is deserved, but you must grant that there are many who do.
Third strike is also a great game, probably responsible for one of the most famous events in competitive gaming but there were some other great games at the time like guilty gear, soul calibur, virtua fighter 4, tekken tag tournament, CvS2 and Marvel 2 and so on. I find it very disrespectful to discard those games because they all had their wonderful moments and compelling gameplay. They all have their flaws but so does melee (poor character viability being the big one.)
I'm not saying that melee doesn't deserve it's pedestal but that the pedestal should be much bigger to accommodate more games.
Back on topic I don't believe the balance changes would make much of a difference, the problems with CoH2 are in my opinion much more fundamental and are:
- The WW2 scenario is not widely appealing. It is a conflict that people around the world still have many issues with, especially in far east asia. People are also still burnt out from the massive amount of WW2 games that were released at the turn of the century. ( Can't really do much about this however it's down to marketing to show gamers that there is a very compelling game to spend their time with)
- It doesn't play like other RTS games, no workers or mining and very hard counters (infantry vs tanks) leads to a very unfamiliar experience to people who are veterans in other RTS games. The only real way to learn how to play the game (unit interactions and what upgrades do) is by playing a lot and learning through trial and error. The game needs to be more transparent in helping people learn the unit interactions and what the upgrades do, with better, more detailed tool tips.
- There's a massive list of micro transactions DLC which influence game play on top of buying the game itself. Which puts off potential players. If you don't buy during a sale you will have to spend $80 to get all four factions and that doesn't give you any extra commanders.
- You need really powerful hardware to get the game to run at a stable and smooth frame rate. Needing more powerful hardware increases the money you have to spend to play the game.
- The UI takes up massive computing power, selecting different units can or opening the tac map can give these really irritating stutters that are detrimental to the game play experience.
- A large amount of bugs that give the player a detrimental feeling while playing, abilities eating ammo but not firing is a big one. Many bugs have been quashed but there are still quite a few in game, many on the trello board.
