Let's make a list of NES Baseball games I'd rather download than 'Bases Loaded'.
Let's see...
Baseball Stars(SNK) and
Baseball Stars 2(SNK), of course.
Then there's the criminally underrated
Little League Baseball(SNK) and
Dusty Diamond's All-Star Softball(Broaderbund).
RBI Baseball(Tengen), though graphically dated, is still one of my all-time favorite sports games.
Bad News Baseball(Tecmo), and
Baseball Simulator 1.000(Culture Brain) were both better as well.
Base Wars(Konami) isn't traditional baseball, but it's a very fun diversion.
Tecmo Baseball(Tecmo) is a comparable game, mainly because it has the same perspective when batting, but the controls were a bit better in this one.
Actually, There's only 5 NES baseball games that I can say are honestly worse(unless you count the 3 inferior Bases Loaded sequels):
Roger Clemens MVP Baseball(Acclaim),
Major League Baseball(Acclaim),
Legends of the Diamond(Bandai),
Baseball(Nintendo), and
Bo Jackson Baseball(Data East). All of them are licensed games except for the 1983 'black cartridge label' dinosaur(which is already available on the Virtual Console, wouldn't you know it).
Bases Loaded was one of the most 'popular' baseball games for the NES at the time, but that's because when it was released(in 1988), there really wasn't a lot of better baseball games to choose from. Can you believe that for nearly the first 3 years of the NES' lifespan, the ONLY baseball game available was 'Baseball'?(Though, football fans had it much worse.) 'Major League Baseball' by Acclaim finally came out around April of 1988, and...well, it was popular based on the fact that it filled a need, and the fact that it used Major League teams and players...but it wasn't very good. Thankfully, RBI Baseball and Bases Loaded were both released 3 months later, and were both much better.
RBI Baseball was the better between these two games, even though the game looked much more dated(It, in fact, was, as it was originally released in Japan in 1986 as
'Pro Yakyuu Family Stadium' by Namco.
'Moero!! Pro Yakyuu', the Japanese version of Bases Loaded was released 6 months later). However, RBI was much more fun to play AND it featured several(but not all) real MLB teams and players.
Bases Loaded was popular because it featured a perspective that was similar to how you would watch baseball games on TV, with the view behind the pitcher. If anything, it was the most 'realistic' early NES baseball game. It also had voice samples that made the experience more realistic. I think the best aspect of the game is provoking the batter to charge the mound by hitting them in the face. Each team has one 'angry' player, and it was fun to find out which one it was.

Bases Loaded is a novelty game. It was unique and impressive at it's time, but it's not worth revisiting, unless you have the need to get all nostalgic over it. But there are so many better baseball games to choose from.
But anyway, Yoshi's Cookie is a fun little puzzler. I just wish it was Dr. Mario or Tetris that was being releasled instead.
